The ghrelin receptors (GHS-R1a and GHS-R1b) - PubMed
WebGhrelin is a 28 amino acid peptide originally isolated from rat stomach. It is cleaved from a 117 amino acid precursor. The human gene encoding a prepropeptide has 82.9% sequence similarity to rat prepro-ghrelin. The sequences of rat and human ghrelin differ by two amino acids Kojima et al (1999). Ghrelin is a participant in regulating the complex process of energy homeostasis which adjusts both energy input – by adjusting hunger signals – and energy output – by adjusting the proportion of energy going to ATP production, fat storage, glycogen storage, and short-term heat loss. The net result of these processes is reflected in body weight, and is under continuous monitoring and adjustment based on metabolic signals and needs. At any given moment in time, it may be in eq… pcs membership contact
