Clinical Significance

C Peptide (C Peptide) is a 31 amino acid peptide, in insulinogen, C Peptide connects the A chain and B chain of insulin, so C Peptide is also called linker peptide. C Peptide is not easily degraded by the liver and its half-life is 5 times longer than that of insulin, and the C Peptide content can more accurately reflect the insulin-secreting function of the body's pancreatic beta cells.
