'''Obestatin''' je putativni [[hormon]] koji se potencijalno proizvodi u ćelijama sluzokože [[želudac|želuca]] i [[tanko crevo|tankih creva]] kod nekoliko [[sisar]]a među kojima je [[čovek]].<ref name="pmid17321609">{{cite journal |vauthors=Gourcerol G, St-Pierre DH, Taché Y | title = Lack of obestatin effects on food intake: should obestatin be renamed ghrelin-associated peptide (GAP)? | journal = Regul.

== Otkriće ==

Istraživanja u Medicinskoj školi [[Stanford (univerzitet)|univerziteta u Stanfordu]] su identifikovala obestatin kao hormon [[2005]]. godine. Do otkrića je došlo korišćenjem [[bioinformatika|bioinformatičkog]] pristupa računarske pretrage sekvenciranih [[genom]]a nekoliko organizama.<ref name="pmid16284174">{{cite journal |vauthors=Zhang JV, Ren PG, Avsian-Kretchmer O, Luo CW, Rauch R, Klein C, Hsueh AJ | title = Obestatin, a peptide encoded by the ghrelin gene, opposes ghrelin's effects on food intake | journal = Science | volume = 310 | issue = 5750 | pages = 996–9 | year = 2005 | pmid = 16284174 | doi = 10.1126/science.1117255 | laysummary = http://nytimes.com/2005/11/11/health/11hunger.html | laysource = New York Times }}</ref>
