01 /What it is
PYY (3-36) is a 34 amino acid endogenous gut peptide fragment cleaved from the longer PYY (1-36) sequence. It is a reference compound in appetite signaling research and is produced by L cells in the distal intestine.
02 /How it works
In research models, PYY (3-36) is studied as a selective agonist at the Y2 receptor in central appetite pathways. Its mechanism is investigated in satiety research alongside GLP-1 and other gut peptides.
03 /What researchers explore it for
Researchers have explored PYY (3-36) in appetite signaling research, in gut peptide research, and in satiety pathway research alongside incretin peptides.
04 /Safety and interactions
Research interactions of note include overlapping pathway engagement with other gut peptides involved in satiety, including GLP-1 analogs. PYY (3-36) is for laboratory research use only and is not for human consumption. Not medical advice. Not intended to diagnose, treat, cure, or prevent any disease.
05 /Research notes
Peptide family: gut peptides, Y receptor agonists. Frequently studied alongside Semaglutide and Liraglutide. The Apothify library lists PYY (3-36) for encyclopedia coverage only.
