What is denaturation of proteins? How is denaturation brought about?OR What is the effect of denaturation on the structure of proteins? |
|
Answer» The press by which the molecular shape of protein changes without breaking the amide / peptide bonds that form the primary structure is called denaturation. OR Proteins gets easily precipitated. It is an irreversible change and the prαess is called denaturation of proteins. Denaturation uncoils the protein and destroys the shape and thus loses their characteristic biological activity. Denaturation is brought about by heating the protein with alcohol, concentrated inorganic acids or by salts of heavy metals. During denaturation secondary and tertiary and quternary structures are destroyed but primary structure remains intact. Example : Boiling of egg to coagulate egg white, conversion of milk to curd. |
