Today we can learn some proteins characteristics from this article.... So let's start 😊
Albumins ➡️
Soluble in water
dilute salt solutions
dilute acids and bases
Coagulated by heat
Globulins➡️
Soluble in salt solutions
insoluble in water
Histones➡️
Basic proteins
soluble in most common solvents
fairly small molecules
Collagens➡️
Resistant to digestive enzymes
insoluble
converted to digestible proteins and gelatins on boiling
contain large amount of hydroxyproline
lack sulfur containing amino acids
Elastins➡️
Partially resistant to digestive enzymes
contain little hydroxyproline
Keratin➡️
Highly insoluble and resistant to digestive enzymes
high cystine content
Nucleoproteins➡️
Salt or basic protein or polypeptide and nucleic acids
Mucoproteins➡️
Protein or small polypeptide containing mucopolysaccharide
hexosamine less than 4%
Glycoproteins➡️
Protein or small polypeptide containing mucopolysaccharide
hexosamine less than 4%
Lipoproteins and Proteolipids➡️
Complexes of protein and lipids having solubility properties of lipids
Chromoproteins➡️
Compounds consisting of proteins and a nonprotein pigment
Metalloproteins➡️
Metals attached to protein
Metals not part of a nonprotein prosthetic group
Phosphoproteins➡️
Phosphoric acid joined in ester linkage to protein
got it 🙂
