[主題詞] C-Peptide
[英文釋義] A 31-amino acid peptide which connects the A and B chains of proinsulin. The exact composition of the peptide is species dependent. In beta cells proinsulin is enzymatically converted to insulin with the liberation of the C-peptide. An immunoassay has been developed for assessing pancreatic beta cell secretory function in diabetic patients in whom circulating insulin antibodies and exogenous insulin interfere with insulin immunoassay.
