Question

Which of the following is/are examples of denaturation of protein?

Options

• Coagulation of egg white

• Curdling of milk

• Clotting of blood

• Both (A) and (B)

Answer 1

Coagulation of egg white

Explanation:

When an egg undergoes a physical change like heating (boiling), the egg white undergoes coagulation because of protein denaturation. In this process, the hydrogen bonds within the protein structure are disrupted, leading to the unfolding of protein globules, uncoiling of the helical structure, and a loss of the protein’s biological function.
