anomaly in the amount in the blood of the connecting (C) peptide that links the A and B chains in proinsulin
Comment:
C-peptide provides a means to promote the efficient folding and assembly of the A and B chains of proinsulin in the endoplasmic reticulum during insulin biosynthesis; after cleavage of proinsulin, C-peptide is stored with insulin in the soluble phase of the secretory granules and is subsequently released in equimolar amounts with insulin, providing an independent indicator of insulin secretion.
