SYNONYMS
GHRP-4, GHRP4.
INTRODUCTION
GH-releasing peptides (GHRPs) are synthetic peptides that like GHRH effect on pituitary somatotrophs to stimulate GH release. The GHRP4 is one of several synthetic met-enkephalin analogs that owns unnatural D-amino acids. They were developed for their growth hormone (GH) releasing activity and called GH secretatogues. They lack opioid activity but are potent stimulators of GH release. These secretatogues are distinct from the growth hormone releasing hormone (GHRH or GHRF) as they share no sequence relation and derive their function through action at a completely different receptor, the ghrelin receptor.
DESCRIPTION
Growth Hormone Releasing Peptide-4 Synthetic is a single, non-glycosylated polypeptide chain containing 4 amino acids, having a molecular mass of 607.73 Dalton and a Molecular formula of C34H37N7O4.
