Peptide YY (3-36) (canine, mouse, porcine, rat) trifluoroacetate salt

Peptide YY (3-36) and peptide YY are both synthesized by the gastrointestinal tract and released into the circulation after a meal. Peptide YY (3-36) is a Y₂ receptor subtype agonist, whereas peptide YY is non-selective for Y₁ and Y₂ receptor subtypes. It has been suggested that Y₁ and Y₂ receptor subtype binding affinities depend on their secondary and tertiary solution state structures.
