Question

Explain denaturation of protein with an example.

Answer 1

Denaturation of proteins is an irreversible change in which proteins get precipitated when they are heated with alcohol, concentrated inorganic acids or by salts of heavy metals. Protein is uncoiled and its shape is destroyed. Characteristic biological activity is lost.
Examples include the following :
(i) Boiling of egg coagulates egg white.
(ii) Milk is converted to curd.
