Characteristics of proteins

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
