Question
Explain denaturation of proteins.
✓

Answer

Due to the physical changes like change in temperature, pressure, or chemical change like change in pH, hydrogen bonds are disturbed. Because of this protein globules unfold and helix gets uncoiled and protein loses its biological activity. This is called denaturation of protein. Denaturation of protein is an irreversible process.
Example : The coagulation of egg white on boiling.
