The structure of insulin consists of two polypeptide chains A and B . These two polypeptide chains

A

Have equal number of amino acids

B

Chain A has 21 amino acids, while chain B has 30 amino acids

C

Chain A has 30 amino acids, while chain B has 21 amino acids

D

Chain A has 11 amino acids, while chain B has 40 amino acids

Text Solution

Verified by Experts

The correct Answer is:
B
Insulin is composed of two peptide chain referred to as A chain and B chain. A and B chains are linked together by two disulphide bonds and an additional disulphide is formed within a species. The A chain consist of 21 amino acid and B chain consist of 30 amino acid.
