The helical structure of protein is stabilised by:

A

dipeptide bonds

B

hydrogen bonds

C

ether bonds

D

peptide bonds

Text Solution

Verified by Experts

The correct Answer is:
B
The helical structure of protein is stablised by hydrogen bonds between amide group of the same peptide chain. These bond are formed by -NH- group of one unit and oxygen of carbonyl group of the other unit. It takes 3.6 amino acid to complete one turn of the helix to enable. such H-bonding and a 13 membering is formed by H-bonding . this H-bonding responsible for holding helix in a position.
