PYY/Peptide YY (3-36), human is a peptide released by cells in the ileum and colon in response to eating that acts to reduce hunger. PYY acts as a hormonal signal from the gut to the brain to inhibit food intake and promote satiety. Low levels of PYY may be a contributing factor in obesity and binge eating, while elevated levels may contribute to anorexia nervosa and decreased bone turnover.
