Pancreatic Beta cell Function and c- peptide
Beta cells of the human pancreas produce and secrete insulin. The product of the insulin gene is a peptide known as Preproinsulin. As with other secretory peptides, the prepeptide or signal peptide is cleaved off early in the biosynthetic process, yielding proinsulin. Proinsulin is an 86-amino acid protein that is subsequently cleaved at two sites to [...]
