Met-Enkephalin Peptide

Met-Enkephalin, also called opioid growth factor (OGF), is a naturally occurring endogenous opioid peptide that has opioid effects of a relatively short duration. It is one of the two forms of enkephalin with Leu-enkephalin. Enkephalins are considered the primary endogenous ligands of the delta-opioid receptor, due to their high potency and selectivity for the site over other endogenous opioids. The Met-Enkephalin Peptide competes with and mimics the effects of opiate drugs.
