The structure of protein that is unaffected by heating is (A) secondary structure (B) tertiary struc — Biomolecules Chemistry Question

💡 Solution & Explanation

When a protein in its native form, is subjected to physical change like change in temperature or chemical change like change in pH, the hydrogen bonds are disturbed. Due to this, globules unfold and the helix gets uncoiled and protein loses its biological activity. This is called denaturation of protein. During denaturation secondary and tertiary structures are destroyed but primary structure remains intact.
