Enkephalin Peptide
Enkephalin is a pentapeptide, it involves in nociception regulation of pain sensation in the body. The enkephalins are endogenous ligands, they are internally derived and bind to opioid receptors. Enkephalin is a neuropeptide, it is an critical signaling molecule in the brain.
There are two forms of enkephalin: Met-enkephalin, Leu-enkephalin.
