C-peptide of human insulin is

A

a part of mature insulin molecule

B

responsible for the formation of disulphide bridges

C

removed during maturation of pro-insulin to insulin

D

reponsible for its biological activity.

Text Solution

Verified by Experts

The connecting peptide or C-peptide is a short protein containing 31 amino acids. It connects the A and B chain of proinsulin molecule. After the processing of proinsulin molecule, C-peptide is removed leaving behind A an d B chains which bound together by disulphide bonds to constitue a insulin molecule.
