Background: C-Peptide

Insulin is a peptide hormone that facilitates the cellular uptake of glucose by regulating the appearance of membrane glucose transporters. The single chain insulin propeptide consists of a 30 amino acid B chain (aa 25-54), a C-peptide (aa 55-89), and a 21 aa A chain (aa 90-110). Removal of the C-peptide by proteolysis enables the formation of mature Insulin, a disulfide-linked heterodimer of the A and B chains. Circulating C-peptide levels are elevated in hyperinsulinism, obesity, and type II diabetes. The human Insulin C-peptide shares 61% and 68% aa sequence identity with mouse and rat Insulin C-peptide, respectively.
