pancreatic polypeptide

pancreatic polypeptide
a hormone released from the delta cells of the islets of Langerhans of the pancreas in response to protein in the small intestine. Its actions are to inhibit pancreatic bicarbonate and protein enzyme secretion and to relax the gall bladder. It belongs to a family of similar hormones that have actions on appetite and food metabolism.

* * *

a hormone (4200 daltons, 36 amino acids) secreted by special endocrine cells in the periphery of some pancreatic islets, the exocrine pancreas, and the intestine; it inhibits pancreatic enzyme secretion and gallbladder contraction, but its physiologic role has not been identified.
