[Trp3,Arg5]-Ghrelin (1-5) is a synthetic peptide fragment derived from the N-terminal region of ghrelin, with substitutions at positions 3 (tryptophan, Trp) and 5 (arginine, Arg). This modified analog is designed to investigate structure-activity relationships (SAR) of ghrelin’s interaction with growth hormone secretagogue receptors (GHS-R1a) and its role in appetite regulation. It serves as a tool for studying the minimal functional domains required for receptor binding and signaling, particularly in obesity and metabolic research.
