Q

C peptide

A

C-peptide is a substance made in the pancreas, along with insulin.

C-peptide test can show how much insulin your body is making.

Good way to measure the level of insulin bc it tends to stay in the body longer.

Q

Amylin

A

Peptide hormone that is consecrated with insulin.

Inhibits glucagon secretion, slows gastric emptying and promoted satiety (satiety hormone) -> prevents post prandial spikes in blood glucose level

Forms amyloid fibrillation deposit in islet cells
