The two polypeptides of human insulin are linked together by

A

phosphodiester bonds

B

covalent bonds

C

disulphide bridges

D

hydrogen bonds

Text Solution

Verified by Experts

The correct Answer is:
C
In humans, insulin is produced by `beta`-cells of pancreas. It is synthesised as prohormone in which two polypeptides are synthesised with an extra stretch of 'C' polypeptide. During maturation extra stretch of 'C' polypeptide is separated and two polypeptide chains (A and B) are linked together by disulphide linkages (bridges).
