Is the connecting piece between insulin molecules. The C-peptide level can be used to gauge insulin production in the body.
A substance that the pancreas releases into the bloodstream as a byproduct of insulin production. The C-peptide level is a rough indication of how much insulin the body is making.
"Connecting peptide," a substance the pancreas releases into the bloodstream in equal amounts to insulin. A test of C-peptide levels shows how much insulin the body is making.
C-peptide is a peptide which is made when proinsulin is split into insulin and C-peptide. They split when released from the pancreas and is released into the blood - one C-peptide for each insulin molecule.
