A 28-amino acid peptide hormone primarily produced in the stomach that stimulates appetite and growth hormone release via the GHS-R1a receptor.
Ghrelin is a 28-amino acid peptide hormone predominantly synthesised by enteroendocrine cells of the gastric fundus, earning it the designation as the 'hunger hormone'. It acts as the endogenous ligand for the growth hormone secretagogue receptor type 1a (GHS-R1a), stimulating both appetite and growth hormone (GH) release from the anterior pituitary gland. Ghrelin undergoes a unique post-translational modification called octanoylation at its third serine residue, which is essential for its ability to bind GHS-R1a and cross the blood-brain barrier. Beyond appetite regulation and GH secretion, ghrelin plays roles in glucose metabolism, gastrointestinal motility, cardiovascular protection, and immune modulation. Synthetic peptides like Ipamorelin mimic ghrelin's GH-releasing action while being more selective for the GHS receptor, avoiding ghrelin's broader appetite-stimulating and cortisol-elevating effects.
A selective pentapeptide growth hormone secretagogue that stimulates GH release via the ghrelin receptor with minimal effects on cortisol and prolactin.
A 191-amino acid peptide hormone secreted by the anterior pituitary gland that regulates growth, body composition, metabolism, and tissue repair.
Growth Hormone-Releasing Hormone, a 44-amino acid peptide produced in the hypothalamus that stimulates growth hormone synthesis and secretion from the pituitary.
A molecule that binds to and activates a cellular receptor, mimicking or enhancing the effect of the natural signalling molecule (ligand).
