C-Peptide (Connecting peptide) is the binding peptide cleaved in proinsulin insulin processing. Responsive immunoassays in blood and urine can easily detect it. Serum C-peptide is a particularly useful marker of endogenous insulin secretion (a synthetic insulin that does not contain C-peptide). A patient is being diagnosed with exogenous (injected) insulin …
