... any pentapeptide endorphin with the sequence Tyr‐Gly‐Gly‐Phe‐Xaa. There are two similar naturally occurring enkephalins, present in brain, spinal cord, and gut; their recommended trivial names are: [5‐leucine]enkephalin ( abbr. : [Leu 5 ]enkephalin or [Leu]enkephalin), Tyr‐Gly‐Gly‐Phe‐Leu (I); and [5‐methionine]enkephalin ( abbr. : [Met 5 ]enkephalin or [Met]enkephalin), Tyr‐Gly‐Gly‐Phe‐Met (II). (II has the same sequence as residues 61–65 of β‐ lipotropin . ) The common precursor of I and II, proenkephalin – itself formed from preproenkephalin...

...enkephalin ( encephalin ) Any of a class of endogenous opioids consisting of five amino acids and found principally in the central nervous system. They bind to opioid receptors , chiefly in the brain, and their release controls levels of pain and other sensations, for example by blocking the release of substance P , a neurotransmitter involved in nociception . Enkephalins themselves can act as neurotransmitters in the brain. See also dynorphin ; endorphin...
