Ghrelin is a 28-amino acid peptide hormone primarily produced by the stomach, unique for its octanoyl modification at Ser3. It is the endogenous ligand of the growth hormone secretagogue receptor (GHSR) and the only known orexigenic (appetite-stimulating) hormone. It plays critical roles in appetite regulation, energy homeostasis, GH secretion, and glucose metabolism.
