The molecule 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 appetite enhancer, an apoptosis inducer, an antineoplastic agent, an antiatherogenic agent and a human metabolite. It is a polypeptide and a peptide hormone.
