MeSH Heading: C-Peptide
Tree Number(s): D06.472.699.587.200.500.250; D12.644.548.586.200.500.250
Unique ID: D002096
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D002096
Annotation: from proinsulin only: not for peptide fragments from other proteins ( = PEPTIDE FRAGMENTS)
Scope Note: 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.
