Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been 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.
