Preproinsulin
Preproinsulin- an insulin precursor consisting -------- NUMBER of amino acids
108
Insulin Gene
located on chromosome NUMBER
Insulin Gene - located on chromosome 11 directs the synthesis of preproinsulin.
Endogenous production of insulin
Estimation of ------------ in the plasma serves as an useful index for the endogenous production of insulin?
C-peptide or connecting peptide - is a short 31-amino-acid polypeptide that connects insulin's A-chain to its B-chain in the proinsulin molecule.

A and B chains in Insulin
A and B chains in Insulin - are connected to each other by------- interchain disulphide linkages
TWO - A and B chains in Insulin - are connected to each other by two interchain disulphide linkages, connecting A7 to B7 and A20 to B19. In addition, there is an intrachain disulphide link in chain
