Compound Summary for: CID 16132309

C-Peptide

Also known as: Proinsulin C-peptide, 59112-80-0
Molecular Formula: C112H179N35O46   Molecular Weight: 2751.82656   InChIKey: XTUNIGNWBZZIPT-NTMYLOQBSA-N
The middle segment of proinsulin that is between the N-terminal B-chain and the C-terminal A-chain. It is a pancreatic peptide of about 31 residues, depending on the species. Upon proteolytic cleavage of proinsulin, equimolar INSULIN and C-peptide are released. C-peptide immunoassay has been used to assess pancreatic beta cell function in diabetic patients with circulating insulin antibodies or exogenous insulin. Half-life of C-peptide is 30 min, almost 8 times that of insulin.   From: MeSH
