What is Ghrelin?

Plain description, key identifiers and synonyms

Ghrelin is a 28-membered appetite-stimulating polypeptide consisting of Gly, Ser, Ser(octanoyl), Phe, Leu, Ser, Pro, Glu, His, Gln, Arg, Val, Gln, Gln, Arg, Lys, Glu, Ser, Lys, Lys, Pro, Pro, Ala, Lys, Leu, Gln, Pro and Arg residues joined in sequence. The O-n-octanoylation of the side-chain hydroxy group of serine-3 (Ser3) is essential for ghrelin's activity. It has a role as an antineoplastic agent, an appetite enhancer, an antiatherogenic agent, an apoptosis inducer and a human metabolite. It is a polypeptide and a peptide hormone.

Ghrelin is a peptide hormone found in Homo sapiens.
