What Size Air Compressor Do I Need for Impact wrench?
What Size Air Compressor Do I Need For Impact Wrench?
To run an impact wrench, it is a big question what size of air compressor do I need for an impact wrench.
After discussing which factors we should consider, let us discover the right one for you which suits your
work. We will also try to recommend the best air compressor needed to run your impact wrench
effectively.
**What is an impact wrench?**
An impact wrench may be a wrench machine designed to deliver high torque output with minimum
effort, by storing energy during a rotating mass, then delivering it suddenly to the output.
**Factors that we should think about before choosing an air compressor**
An air compressor is a widely used tool both in commercial and personal matters. This is a
pneumatic device that converts power into potential energy which is stored in pressurized air. Here
two factors that determine the effectiveness of an air compressor. These are CFM and PSI.
CFM means Cubic Feet per Minute. It may be defined as the measurement of the velocity at which
air flows into or out of space. Saying about impact wrench, air compressors are needed that can
create 2-16 cubic feet per minute airflow for different types of impact wrench. We will discuss it
later.
PSI stands for pound-force per square inch. This is a unit of pressure that is taken into account to
evaluate the power of the air compressor (How much air pressure they produce). Different sizes of
impact wrenches require an air compressor with roughly 90-125 PSI air pressure.
If we randomly pick an air compressor without considering the CFM, PSI, and tank size that would
result in a worse performance. Instead choosing the best suit may result in more output.
Now, after discussing CFM and PSI, let us correlate it with the specific size of the impact wrench. As
you know there are different sizes of an impact wrench and each of them needs different power of
air compressors. The smaller one may need an air compressor with less CFM and PSI while a larger
one needs more. 125 PSI air pressure is a waste for a 1/2 inch impact wrench, but 2-3 CFM air
compressors may not be able to operate a 3/8 inch impact wrench. So, let's discuss individually the
best air compressor for different types of the impact wrench.
**1/2 inch impact wrench**
Let's start with the most common one. Among all sizes of the impact wrench, 1/2 inch is widely
used, maybe it is more popular than any other wrench. So, it is necessary to find the best suit for
this type of impact gun. For a 1/2 inch impact wrench, it is wise to use an average air compressor
midway between 3.5 to 5 CFM. Also, this compressor should have the power of creating 90-100 PSI
air pressure. At least 4 CFM air compressors should be used for safety. One can enjoy a good
balance of everything and the best quality performance using a 5 CFM air compressor for a 1/2 inch
impact wrench.
**1/4 inch impact wrench**
This is a small size of impact wrench which does not require a lot of pressure. So, what size of air
compressor do I need for a small size impact wrench? An air compressor that is capable of creating
only 1-1.5 CFM and at least 90 PSI air pressure is enough to operate this kind of an impact wrench.
For a 1/4 inch impact wrench using more pressure air compressors may be a waste.
**3/8 inch impact wrench**
A 3/8 inch is worthy of a little bit more power. An air compressor less than 2.5 CFM is not perfect
here. Though 2.5 CFM air compressors may work, it is also not recommended. An air compressor
that is capable of delivering 3 to 3.5 CFM and at least 90 PSI air pressure is acceptable.
**Final talk about what size of an air compressor do I need for a 1-inch impact wrench**
This kind of impact wrench is not for household work. These are only worthy for construction use.
One inch impact wrench is not seen typically. As it is a big size, it needs a heavier investment. One
can go for an air compressor between 9-10 CFM range and that tool should be capable of creating
at least 90-125 PSI air pressure.
**What tank size of air compressor do I need for an impact wrench?**
However, talking about air pressure is not enough to conclude. We should consider the size of the
gallon to choose the best air compressor. Air compressors differ by their Gallon sizes. Talking about
the minimum, a 6-gallon air compressor with 3.5 -5 CFM is necessary to operate an impact wrench.
But this is not sufficient for day to day work, let alone professional work. To clarify, the larger the
size of the gallon, the better the performance of the air compressor. But the cost matters.
A 3-gallon air compressor cannot operate an impact wrench at all. Because it is only capable of
creating 0.5 CFM air pressure, but the minimum air pressure needed to operate an impact wrench
is about 1 to 1.5 CFM. Though a 3-gallon air compressor is cheap one should not choose it. A 6-
gallon air compressor may be able to run an impact wrench but it is the minimum size. So using this
size of air compressor will result in an interruption. After working a small-time, stored air may run
out. As we know there exist 1 to 60 gallons tank size air compressors but it is wise to use a definite
size of air compressor which meets one's requirement. Suppose, for personal use, one can
recommend a 10-gallon size air compressor. But for professional use, it needs much more
investment which is about a 20-gallon air compressor.
**Recommended air compressors**
At last, we can recommend here some best air compressors for impact wrench.
These are
1. Eagle EA - 5000 Air Compressor
2. DEWALT Air compressor
3. Makita MAC5200 Air compressor
**Final Word**
The question of what size air compressor do I need for an impact wrench may be concluded with the
result that an air compressor with 5-8 CFM and gallon size between 20- 30 is recommended. While 3-4
CFM with 6-8 gallon is the minimum requirement. But who needs heavy use may go for further
investment and use as much as 60- 80 gallons.
Hello guys, how are you feeling in this rainy season?? Whole day is now raining. Any way I enjoy this day specially when i am in home. And now in this free time i love sleeping 12 hours + and the sky is crying....
Also its a great pleasure to write and earn from read cash enjoying the rainy scene.
Learning is fun ( phosphate in our body)
Hello readcashers, are you ready to learn about an important electrolyte in our body named phosphate?
So lets start our journey...
Today, I was talking with one of my nerd friend and that was a great mistake for me. Nothing bro, just I said what if there is no phosphate in our body??
Okay, my friend started....
What do you think from where you get your energy which you use for daily household work purposes??
Oh! Dear friend please dont start your lecture here..
No, no am not starting.. please answer.
Okay
--Adenosine tri *(phosphate)*
--Nicotinamide adenine di nucleotide *(phosphate)*
-- Can you mention two importamt component of your bones? ?
Calcium and *(phosphate)*
[ 85% of phosphates are in bone and they combine with calcium to form hydroxyapetite which make bones hard, 1% in ECF and 14 % intrecellular.]
--what about your teeth? Isnt there phosphate ?
-yeah, of course
- so let me tell you about some very very important functions of phosphate in our body...
*Functions of phosphate*
1. Bone mineralization
2. Participate in energy metabolism( storage and transfer of energy as ATP)
3. Act as buffer and facilitate urinary excretion.
4. Act as the component of intracellular second messenger and participate in signal transduction.
5. Facilitate respiratory chain activity.
6. Component of phospholipid, nucleotide and nucleic acid.
7. Component of 2, 3-BPG and regulate oxygen transport.
8. Helps in regulation of enzyme activity by covalent modification of enzyme.
- bro!! Please stop! I cant remember more functions
--okay, then i gonna explain the regulatory mechanism of it. Do you have patience to stay with mem
-Wait! You didnt said about normal range of phosphate. What I will regulate here ?
--okay, am saying ..
◇Normal range of phosphate:
--listen, phosphates are present in the kids body 4-7 mg/dl
-- phosphates are present in the adults body 2.5- 4.5mg/dL
Now, say if phosphate increases then what should I do??
-- uhh, you have nothing to do. All the functions will be carried by calcitriol and parathyroid hormone.
You just see
FIG-1
( regulation of phosphate concentration in case of hypophosphayemia )
&
(FIG-2 regulation of phosphate concentration in case of hyperphosphayemia )
--Does phosphate concentration increases above 4.5 mg/dL
- yes , we call it hyperphosphatemia
-when it occurs?
-Listen
Causes of hyperphosphatemia
1. Chronic kidney disease
2. Hypothyroidism
3. Pseudohypothyroidism
4. Excessive intake
5. Breakdown of cells because inside cells there are plenty of phosphates
So due to some causes like
a. Crush injuries
b. Tumor lysis syndrome
c. Rhabdomyolysis( Destruction of muscle cells)
Hyperphosphatemia may occur.
What is the problem if Hyperphosphatemia
Occurs ?
If it is mild then no problem but if is severe cases many symptoms are appeared.
Symptoms of severe hyperphosphatemia:
+ Neurons become more excitable.
+ Tingling around mouth.
+ seizures
+ Bone pain
+ Binds with calcium and forms bone like crystals
a. Under the skin
b. Blood vessel walls.
c. Joints
d. Kidney stones
e. Long term hyperphosphatemia >>whole kidney turns to bone ☆( Nephrocalcinosis)☆
--Huh! You converted the whole kidney to a piece of stone ?? What a danger man ?
-Now tell me , does phosphate concentration decreases below normal?? ----Yes we call it Hypophosphatemia
Causes of hypophosphatemia:
1. Excess loss of phosphate
2. Primary hyperparathyroidism
- excess phosphate lost in urine
3. Fanconis syndrome
- (PCT cant reabsorb PO4)
4. Not enough abosorbed in GIT
For alcohol & some medication.
5. Deficiency in Diet
- Malnourished
- Anorexia Nervosa
6. Respiratory Alkalosis
Do you know?
Symptoms of severe hypophosphatemia:
▪Muscle weakness
▪Osteomalacia
▪Muscle breakdown
▪altered mental status
Also
▪ hypercalcemia symptoms
Did you understood abc of phosphates in our body ??
Will you ask again what is the use of phosphate in our body??
This story is hypothetic. I build this story to share knowledge via fun.
Please dont forget to share your opinion and dont left no stone turned unturned to know more about inside your body...

Journey inside disease(Diabetes Mellitus-2)
Hello learners
This is my second day with you to travel inside a disease **Diabetes Mellitus**.
Incase you missed my previous writing you can find it here.
**Journey inside disease(Diabetes Mellitus-1)** https://read.cash/@Saleh123/journey-inside-diseasediabetes-mellitus-1-48613eef
Today we gonna focus on how to diagnose it..
So Lets dive in....
**Diagnosis of diabetes mellitus**
I hope readers will find easy to explain biochemical results and will be able to diagnose diabetes mellitus on their own.
*There are 3 ways or 3 diameters to confirm the diagnosis of Diabetes Mellitus.*
The first one-
1. **Fasting blood sugar level or (FBS** )
- more than or equal to 7 mmol/L
Or
- more than or equal to 126 mg/dL
The second diameter which we can use is
2. **Oral Glucose Tolerance Test or ( OGTT)**
- more than is equal to 11.1 mmol/ L
- more than or equal to 200 mg/dL
And the last one is
3. **HbA1C( Glycosylated hemoglobin A 1C**)
- more than or equal to 6.5%
Do you know the normal levels of blood sugar level in your body. Incase answer is no lets proceed.
Very very important to remember is
**Normal value of blood sugar level:**
1. Fasting blood sugar level- 3.5- 6.1 mmol/ L
2. Random blood glucose level- 3.5 - less than 7.8 mmol/ L
3. Glycosylated hemoglobin A 1 c ( HbA1C) is less than 5.7 mg/dL
Now you can check your own blood sugar level in nearby diagnostic center and be sure your blood sugar level is within the normal range. Because increased blood sugar level have various bad effects on your health. Which we gonna discuss later.
Previously I talked about a test named *****OGTT*****. Many of you may find this term new and today I gonna dive inside this test.
****Oral Glucose Tolerance Test****
What do you think when will your doctor advise you for OGTT. Well, theres some conditions behind them. Lets understand
**Indication of OGTT:**
1. If fasting blood suvar more than 6.1 mmol/L to less than 7 mmol/ L we should go for OGTT.
2. If random blood sugar level is 7.8 mmol/ L to 11mmol/L.
3. To diagnose pre diabetes OGTT is done.
Pre diabetic condition:
a. IFG( Impaired Fasting Glucose)
b. IGT ( Impaired Glucose Tolerance)
4. Also OGTT is done to diagnose gestational diabetes mellitus.
Like many other biochemical tests OGTT also has some prerequisites too..
**Prerequisites of OGTT**:
But before doing Oral glucose tolerance test we should consider the following;
1. Discontinuation of medication known to effect glucose tolerance.
( Note: we must stop using drugs that hamper glucose metabolism 7 days before ogtt is done
These drugs include: thiazides, corticosteroids, OCP-oral contraceptive peal. )
2. Test should be performed in the morning after 3 days of unrestricted diet and unrestricted activity ( unrestricted diet means having 150 gm of carbohydrate per day)
3. Test should be performed after 10 hours of fasting. Guys, this is an important matter to keep in mind.
4. Incase of hospitalized patient or hospital admitted patient this test cannot be done.
Readers here I wanna ask you a question can you guess why? Why OGTT cant be done for hospital admitted patients.
5. Test should be performed without smoking cigarettes.
***Readers, please dont feel bored. Just follow me and we gonna discover deeper inside of OGTT.***
Now we have gained idea about why when and before what we should have our ogtt done .
Lets have a look about the roadmap of this test.
**Procedure of OGTT:**
1. Test should begin between 7 am to 9 am.
2. 10 hours fasting is mandatory.
3. Estimation of fasting blood sugar level.
4. Recommended glucose load is 75 gram dissolved in 300 ml of water and ingested over 5 minutes.
5. Two hours after oral glucose intake again blood sample is collected and estimation of blood glucose level.
Simple, our oral glucose tolerance test is over. Now lets wait for the result. I wish everyone have positive result then.
But today I will not discuss about the interpretation of the result of OGTT. You must wait for
***Journey inside disease( Diabetes Mellitus-3)***
Hope I will meet you soon. Till then be healthier.

Is it wise to have an icecream when we feel hot???
Hello readcashers,
Lets learn together. Today I want to ask you an interesting question.
What do you think ? Is Ice cream for hot weather countries like middle east (saudi arab, qatar, dubai) or for cold weather countries like westerns ( newzealand, UK, spain) . Do you think people of hot climate should love ice cream ?
Lets come to the answer. If you thought that it is wise to have ice cream when you are feeling hot then you are doing a mistake.
May be you are surprised. Let me collaborate. To understand why am I saying that you should not have the taste of ice cream when you are feeling hot, you have to think a little bit in past. We should go through the history of ice cream.
In cold countries, people used to eat cream in their meals. Creams contain lipid and fatty substances, which when digested and assimilated, yield high energy and produces heat. So to increase body temperature they were eating creams. As they have plenty of ice they used to mix creams with ice to have a better test. From that icecream came.
But now we dont go through the whole matter. When we feel hot, we just rush to nearby market, buy an icecream. Immediately as ice cream contains ice we feel cold and releif from hot but consequently when it is digested, it yield high energy and heat produced.
Thats I wanna say you guys, we should not buy an ice cream when we are feeling hot.
Guys, learning doesnt have any limit, any place, any age.
I learned this interesting matter from my younger brother and you gonna learn it from your smartphone where many peoples use this device for nothing.

Journey inside disease(Diabetes Mellitus-1)
Hello learners
Before I start my journey I wanna thank 2 great writers in read cash from whom I really got inspiration to write about diseases. First one is @Jane from whom i took advice at first. And second one is @Hanzell because reading hanzells articles brought be inspiration to start writing academic articles.
Today i am going to travel inside a most common disease from which most of us or our parents, our relatives suffers a lot. May be some of you can guess which disease I wanna mean. The dangerous *****Diabetes Mellitus*****.
Many people says that diabetes mellitus is the root of many many principal diseases. Again many of them wanna refer it as a morbid disease.
So lets proceed in....
The diabetes mellitus
**Definition of diabetes mellitus**: A group of metabolic disorders of carbohydrate metabolism in which glucose in underutilized producing hyperglycemia.
Or
Lets see another definition
Diabetes mellitus is a heterogenous group of multifactorial, polygenic syndromes charecterized by elevation of blood glucose caused by a relative or absolute deficiency in insulin.
**Note**:here ***multifactorial*** means mixture of different differnet causes genetic and environmental. Examples of some diseases are diabetes mellitus, hypertension etc.
***Polygenic*** means multiple genes involved.
***Syndromes*** means not a single problem together many problems
***Insulin deficiency*** may be absolute or relative. Absolute deficiency means decreased insulin secretion from pancreas(normally 250-300 unit secretes) normally tgese type of diabetes is type 1 diabetes.
Relative deficiency means insulin resistance normally these types of diabetes is called type 2 diabetes.(usually after age 60 type 2 diabetes occurs)
Now come to the classification of diabetes
****Classification of diabetes mellitus****:
1. Type-1 diabetes mellitus
2. Type-2 diabetes mellitus
3. Other specific types of diabetes mellitus
4. Gestational diabetes mellitus
(Who doesnt have diabetes mellitus before but in pregnancy 1st diabetes recongnized )
Now lets collaborare each types of diabetes
1. **Type- 1 diabetes mellitus**
**Causes**:
a. absolute deficiency of insulin caused by autoimmune attack on beta cells of pancreas.
b. Some have no evidences of autoimmunity and classified as type 1 idiopathic (cause is unknown)
**Charecteristics**:
- They have insulinopenia( deficiency in insulin)
-seventy five percent occurs before the age of eighteen
-five to ten percent of all cases of diabetes are in this group.
2. **Type-2 diabetes mellitus**
90% of all cases of diabetes are in this group.
**Causes of type- 2 diabetes mellitus**
1. Insulin deficiency
2. Dysfunctional beta cells of pancreas
May be many of you ask me what is isnulin resistance. Is it fighting against insulin. Ha ha ha. May be something like that.
Let me clear it to you
**Insulin resistance**
**Definition of insulin resistance**
Its is the decresed abilty of the target tissues such as liver adipose tissue and muscles to respond properly to normal or elevated circulating concentrations of insulin.
Its is **charecterized** by uncontroled hepatic glucise production and decrese glucose uptake by muscle and adipose tissue. ( because of decreased insulin dependent glut 4
-Source lipincott of biochemistry)
**Causes of insulin resistance**:
1. Obesity
2. Gestational diabetes mellitus
3. PCOS ( poly cystic ovary disease)
4. Growth hormone excess
3. Other types of diabetes mellitus
Important Causes of them :
1. Genetic defects if beta cell function
2. Geentic defects in insulin action.
3. Disease of the exocrine pancreas.
4. Endocrinopathies
A. Cushing syndrome ( steroid increses drastically )
B. Acromegaly ( increased growth hormone)
C. Glucagonoma ( glucagon secreting tumor )
5. Administrations of hormones of drugs known to induec beta cell dysfunction (dilatine, pentamadine ) or impair insulin action.
( 1. Glucocorticoids, thiazides, beta adrenergics or beta agonist )
6. Infection
7. Uncommon forms of immune mediated diabetes.
8. Other genetic conditions( example: down syndrome, kline filter syndrome)
I think you are bored today, let me continue it tomorrow. thanks for patience.

Circulation-1(systemic and pulmonary circulation)
Hi learners, hope all of you have a good time. At first I wanna thank @OverThinker for giving me inspiration to write and then i can start my todays article. Hope you will find it helpful for all.
****Circulatory systems of the body****
****Source of figure: guyton physiology page 171****
Do you know there are 2 types of circulatory system in our body.
****1. Systemic circulation****
****2. Pulmonary circulation****
**Systemic circulation** refers to the circulation which starts from the left ventricle and ends at right atrium.
**Pulmonary circulation** refers to the circulation which starts at right ventricle of the heart and ends at left atrium.
***Systemic circulation***: here from the left ventricle through the aorta oxygenated blood is ejected and conveyed to the whole body via aorta-arteries-arterioles-capilliaries. However, then the body tissues utilizes the oxygenated blood and the blood becomes deoxygenated as it has losed its oxygen. These bloods are than collected by the venules-veins and at last via inferior vena cava, superior vena cava and thebasic veins deoxygenated bloods reaches the right atrium of the heart.
From the right atrium of the heart the blood rushes to right ventricle passing through the tricuspid or semilunar valves.
Now here in the right ventricle these bloods are deoxygenated so it needs to be oxygenated. For that purpose, it moves through the pulmonary artery towards the lungs (right and left) .
(*****Note*****: here pulmonary arteries contains deoxygenated blood where all other body arteries contain oxygenated blood. Dont worry this is the only exception you have to remember.
Again pulmonary vein is the only vein to contain oxygenated blood whereas all other veins of the body contain deoxygenated. This is also an exception.
You can note it as it might be helpful for you in the next.
So definition of artery can be the blood vessel which comes out from the heart . And the veins are the blood vessels which ends towards the heart
Nor the definition should emphasize that which blood vessel contain oxygenated or deoxygenated.
I hope everyone can understand this. If not, feel free to leave a question in the comment box. I will appreciate your desire to learning)
In lungs these bloods remove carbondioxide out via air during each breath and they take up oxygen and become oxygenated. About 40 milliliters of oxygen ( O2) is absorbed for each liter of blood. So in total for 5 liters of blood about 200 mililiters of oxygen is absorbed. Then these oxygenated blood reaches the left atrium of the heart via the pulmonary vein. Here pulmonary circulation ends and systemic circulation again starts from the left ventricle.
Systemic circulation again starts its quite true but I dont want to lose your time anymore.lets end here today.

Online Essay contest (I have secured second position)
Hello readcashers, today I am very happy. I winned 2nd prize in online essay contest. I wanna share with you guys, my story behind that.
All praise is to allah. I have winned the second prize in essay contest in category (A ) which is arranged by my medical college (faridpur medical college).
This was an online essay contest arranged for ****National Mourning Day**** of my country Bangladesh.
Our National Mourning day is **15 August**. There is a miserable history behind this.
**Bangabandhu sheikh mujibur rahman**, ***Father of the nation***, was **killed** in 15 august, 1975 along with 18 family members by some cruel people. 10 years child sheikh rasel also cant escape from their brutual bullet. They didnt allow this little child to live.
From that miserable history national mourning day of bangladesh is selected 15 august. Every year peoples of bangladesh remember their great leader in 15 august. It is a national holiday also.
However many academic institutions organize different different cultural programmes, competitions such as essay contest, recitation of poem etc.
For little kids they also arrange mujibs picture drawing contest as well.
Like many other institution my campus, my medical college also have arranged an online **essay contest** about **bangabandhu and liberation war 1971**. It was an **online contest** because due to corona situation its not possible to arrange offline programme. There is no one in the campus 😀
There was 2 category
Category A for batch F 28 and F29
Category B for batch F25, F26 and F27
As I am of batch F28 I have been participated in category A.
They told me to write the essay in no more than 3500 words. However, it was not possible for me to pass the 600 words. I can hardly write about more or less 650 words. I wrote the essay on A4 paper and as their requirement I send it to my college principals email.
I was totally hopeless. I didnt thought that my essay can win a contest as of I have written only a little(600 words). But now i beleive that quality is main not the quantity. None can attract judges mind by quantity without a quality.
10 days layer, at 31 august suddenly I recieved an email from principal sir. He gave me an file. I open that file and I see it was credited to me as a recognization of participation in essay contest by faridpur medical college. That certificate was so much attractive in view. I thought in mind that what ever I win or not I have earned an certificate of participation which is really amazing. I asked my friends any of them have participated or not. Swarnali replied she has.
Than I thought it would take a number of months to publish the final result but yesterday was the result published. At 6 pm i get up from bed, suddenly I opened the phone and see there are plenty of messages about
*****Congratulation saleh mohammed*****.
I wondered what happened. Then I opened messenger group and I found this official notice of Fmc where the result of essay contest is published. All praise is to Allah that my 600 words has got the 2nd position in Category A. One of my junior who is very much talented secured the 1st position.
Here my medical college said that prize giving ceremony date will be informed later.
Good wishers, I hope you will keep me in your prayer.
If you wanna read more articles please *****dont forget to subscribe*****, *****like this article and share your opinions.***** I gonna begin writing medicine related articles. I hope I will start with a most common, suffering disease The **Diabetes Mellitus**.
Thanks for your patience.

A rainy day is the day in which all the day rains a lot.
Sunshine can be hardly seen. Many people enjoy these types of days whereas some people dont like those days.
Here i shared some of the captures of my own todays rainy day
However i like rainy days a lot. Its a great pleasure for me to see a sky where sun cant be seen and the sky is full of clouds.
There are myths in rural area that due to rainy day old peoples feel bath pain. Young people specially childs rainy days.
Visual cycle,Dark adaptation, light adaptation
Hello learners, I hope all of you are having a good time and have a good eye to read my article. Good eye !!!!!!! That may be seems funny but soon you will understand why I have said that. Actually today I want to discuss about how vitamin A helps in vision and how deficiency of vitamin A in diet can cause night blindness. Lets proceed-
( do you want to learn more about vitamin A
Have a look to my another 2 articles about vitamin A
1. *****Overview of vitamin A*****
https://read.cash/@Saleh123/overview-of-vitamin-a-967d40dd
2. *****Functions of vitamin A*****
https://read.cash/@Saleh123/functions-of-vitamin-a-8534939b)
********Visual cycle (rhodopsin cycle):How vitamin A helps in vision and prevent night blindness********
1. Visual process involves vitamin A containing visual pigments present in photoreceptor cells( rods and cons ) of retina.
2. Visual pigments are basically conjugated proteins consisting of opsin(protein) and 11-cis retinal (Prosthetic group).
3. Vsiual pigments present in rods Is called rhodopsin which is most light sensitive and helps in dim light vision.
*(Mnemonic: remember ro(d) =(d)im light )
4. Visual pigments present in cons is called Iodopsin which is responsible for bright light vision and color vision.
*(Mnemonic: remember (c)ons =(c)olor vision )
5. In response to light waves visual pigments(rhodopsin, iodopsin ) belaches to opsin and all trans retinal through a series of photochemical isomerizations.
This photolysis of visual pigments initiates visual signals (nerve impulse) in photoreceptor cells that finally helps in vision.
6. Most of the all trans retinal produced by bleaching of visual pigment is isomerized back to 11 cis retinal directly or indirectly via retinol to resynthesize the visual pigment. Part of the all trans retinal is lost and not available for resynthesis of the visual pigments, so it needs to be make up from dietary vitamin A in the form of all trans retinol which is isomerized to 11-cis retinol and then dehydrogenated to 11- cis retinal to form visual pigments.
7. Therefore, continual supply of retinol is essential for normal visual function.
Retinol deficiency depresses the resynthesis of visual pigment and interferes with the function of photoreceptors particularly rods causing ****night blindness.****
Now lets discuss about another important topic(light adaptation / dark adaptation)
*****Dark adaptation/ light adaptation*****:
1. If a person spends a considerable length of time in bright light and then moves to a dim light environment, gradually visual pigments(rhodopsin) concentration in rods and cons increases. As a result visual threshold decreses and the retina slowly become more sensitive to light so that it can respond to the light of low intensity to allow vision. This is called dark adaptation.
2. In bright light,visual pigments(rhodopsin) in rods and cons undergo photolysis(bleaching) to retinal and opsin reducing its concentration. This causes reduction of the sensitivity of eye to light that raises visual threshold so that eye can respond to the light of high intensity. This is known as light adaptation.
3. When individual goes to dim light the retinal and opsin recombine to build up rhodopsin store necessary for the optimal function of rods and cones at low intensity light. The time needed to build up the necessary rhodopsin store is the time required for dark adaptation.

*functional forms:
1. Retinol
2. Retinal
3. Retinoic acid
But still there is an inactive form of vitamin A which is called provitamin A or Beta carotene. Beta carotene is found in plants whereas other functional forms of vitamin A found in animal sources.

As vitamin A has several important functions in our body less intake of it causes several deficiency symptoms:
These can be devided into 2 groups

c. Night blindness
And finally and gradually if symptoms were not treated earlier
d. Full blindness
2. Extra ocular menifestation:
a. Dry and scaly skin
b. Keratinization of epithelial cells of Gastro Intestinal Tract.
* Sources:Lets have a look to the souces of vitamin A so that we dont miss this so important vitamin in our diet.
1. Animal sources: vitamin A is widely distributed in animal sources rather than plant sources.
a. Egg
b. Meat
c. Fish
d. Liver
e. Fish oil (e.g. cod liver oil)
2. Plant sources: Vitamin A is also present in some plant sources as well.

Coursera (part 1)
In the era of 2020 it is very easy to learn something new, to gather knowledge from worlwide resources simply sitting in your own home.
Learning out of the box is very very important for now. Even many people are curious also. For instance in the past if anyone wants to be familiar with programming he must have a fight. But now one can master codes of programming, programming languages java,c++, python through online courses only.
There are hundreds of websites which offer online courses with a variety of subjects, topics, life skills and so on.
Coursera is one of the best of them. Edx, udemy are also some example.
Coursera is best one because here instructors are only from leading universities worlwide (e.g. harvard university, duke university, cambridge university etc.) and from best companies like google, IBM etc.
Another fact is that it provides courses free of cost. You can get access to all study materials but if you want certificate you have to lose your pocket. But there is also a solution.....
(To be discussed in part 2)
