Peptid YY je kratak (36-aminokiselina) protein koga oslobađaju ćelije ileuma i debelo crevo u responsu na unos hrane. Kod ljudi on umanjuje apetit. On je takođe poznat kao PYY, peptid tirozin tirozin, ili pankreasni peptid YY3-36.[1]

Struktura[uredi - уреди | uredi izvor]

Peptid YY je srodan sa pankreasnom peptidnom familijom, jer je 18 od njegovih 36 aminokiselina locirano u istim pozicijama kao kod pankreasnog peptida.[2] Postoje dve glavne forme peptide YY: PYY1-36 i PYY3-36 koji imaju PP strukturni motiv. Međutim, najčešća forma cirkulišućeg PYY je PYY3-36, koja se vezuje za Y2 receptor (Y2R) Y familije receptora.[3] Peptid YY3-36 (PYY) je linearni polipeptid koji se sastoji od 36 aminokiselina.
