[Leu5]-Enkephalin（Cat No.:P000124）, is a pentapeptide and a naturally occurring opioid peptide found in the human body. It belongs to the enkephalin family of neuropeptides, which act as neurotransmitters and neuromodulators in the central nervous system. [Leu5]-Enkephalin specifically contains leucine (Leu) as its fifth amino acid. This peptide has analgesic (pain-relieving) properties and binds to opioid receptors in the brain and spinal cord, modulating pain perception. Research on [Leu5]-Enkephalin has contributed to our understanding of the endogenous opioid system and its potential implications in pain management and neurobiology.
