Pancreatic Polypeptide
Pancreatic Polypeptide increases gut motility and gastric emptying, stimulates the secretions of the intestinal hormones like gastrin, secretin and CCK.
Pancreatic polypeptide is a peptide hormone, containing 36 amino acids and secreted by the stimulation of F (PP) cells in the islets of Pancreas.
It is related to two other 36 amino acid polypeptides – polypeptide YY (PYY) of intestine and neuropeptide Y (NPY)of brain and ANS.
It inhibits pancreatic enzyme secretion and gall bladder contraction. Somatostatin inhibits its release.
