Biomolecules · Class 12 · JEE Main Previous Year Question
The secondary structure of protein is stabilised by:
- a
Peptide bond
- b
Glycosidic bond
- c✓
Hydrogen bonding
- d
Van der Waals forces
Hydrogen bonding
Step 1: Secondary Structure Formations — Secondary structures refer to repetitive patterns like -helices and -pleated sheets.
Step 2: Stabilizing Interaction — These patterns are maintained by hydrogen bonds between the amide groups () of the peptide backbone.
Step 3: Result — Hydrogen bonding is the key stabilizing force at this level. Correct option is (c).
Remember: The primary structure is stabilized by covalent peptide bonds, not hydrogen bonds.
