Enkephalin
Overview
Enkephalins are pentapeptide endogenous opioid ligands that play a fundamental role in regulating nociception and pain sensation. They exist in two primary forms—Met-enkephalin (Tyr-Gly-Gly-Phe-Met) and Leu-enkephalin (Tyr-Gly-Gly-Phe-Leu)—both binding to δ- and μ-opioid receptors as critical signaling molecules in the brain and peripheral nervous system.
