Q6 / 90 · JEE Main 2021 (16 Mar Shift 2) · Chemistry

The secondary structure of protein is stabilised by:

A
Peptide bond
B
glycosidic bond
Correct answer
C
Hydrogen bonding
D
van der Waals forces

Solution

The secondary structure of protein includes two type :

(a) $α$ -Helix

(b) $β$ -pleated sheet

In $α$ -Helix structure, the poly peptide chain is coil around due to presence of Intramolecular $H$ -Bonding.

Hence, the correct answer is option: 'C'.
