Peptide YY (PYY)
Peptide YY (PYY) is a peptide produced in the small intestine and colon that reduces appetite in response to feeding. PYY is a linear polypeptide consisting of 36 amino acids with structural homology to NPY and pancreatic polypeptide. PYY exerts its action through NPY receptors, inhibits gastric motility, and increases water and electrolyte absorption in the colon. PYY may also suppress pancreatic secretion. It is secreted by the neuroendocrine cells in the ileum and colon in response to a meal and has been shown to reduce appetite. Research has also indicated that PYY may be useful in removing aluminum accumulated in the brain.
