Insulin is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats; in addition, it stores fat to be used for energy later. When you eat, your blood sugar increases, which causes insulin to be released.
C-peptide is a biologically inactive peptide formed when beta cells of the pancreas convert proinsulin to insulin. Most of C-peptide is excreted by the kidneys.C-peptide levels usually correlate with insulin levels and provide a reliable indication of how well the pancreatic beta cells secrete insulin.-peptide is a biologically inactive peptide formed when beta cells of the pancreas convert proinsulin to insulin.
