Chemical Description
GHRP-6 is a synthetic Met-enkephalin analogue comprising six amino acids (hexapeptide). Unlike endogenous Growth Hormone-Releasing Hormone (GHRH), GHRP-6 does not act on the GHRH receptor but instead binds selectively to the Ghrelin Receptor (GHSR-1a). Biochemically, this binding event triggers a signal transduction cascade involving Protein Kinase C (PKC) and IP3, leading to the depolarization of somatotroph cells and the release of growth hormone vesicles in vitro. It serves as a fundamental model for studying non-GHRH mediated endocrine regulation.
Research Applications
This compound is strictly for laboratory research use in the study of:
