Significance and Normal Values of C-Peptide Release Test
C-peptide is a secretion product of pancreatic β-cells, and it shares a common precursor with insulin—proinsulin. One molecule of proinsulin, under specific conditions, splits into one molecule of insulin and one molecule of C-peptide; therefore, theoretically, C-peptide and insulin are secreted in equal amounts. The physiological functions of free C-peptide in the blood are not … Read more
