Biochem/physiol Actions

In proinsulin the insulin A and B chains are linked by C peptide. During the biosynthesis of insulin, the C peptide promotes proper protein folding and disulfide bond placement after which it is cleaved. The cleaved peptide may inhibit insulin aggregation and is stored and released from the β cells with insulin in a one-to-one molar ratio. C peptide is a marker for β cell function in vivo; levels are enhanced in insulin resistance or insuloma and reduced in insulin insufficiency (type I diabetes). C peptide may alleviate the vascular damage and neuropathy associated with insulin depletion.
