Correct Answer » A Explanation |

Ans. ‘A’ Pro-insulin
- The proinsulin molecule undergoes a series of site-specific peptide cleavages that result in the formation of equimolar amounts of mature insulin and C-peptide.
- Proinsulin has about one-third biological activity as that of insulin.
- Measurement of C-peptide is an index of the rate of secretion of insulin.
