methionine enkephalin-lys

Description:
Methionine enkephalin-lys, also known as Met-enkephalin-lysine, is a peptide that belongs to the class of endogenous opioid peptides. It is composed of five amino acids, specifically tyrosine, glycine, phenylalanine, leucine, and methionine, with a lysine residue at the C-terminus. This peptide is known for its role in modulating pain and stress responses in the body by binding to opioid receptors, particularly the delta-opioid receptor. Methionine enkephalin-lys exhibits analgesic properties and is involved in various physiological processes, including mood regulation and the modulation of the immune response. Its structure allows it to interact effectively with receptors in the central nervous system, contributing to its biological activity. Additionally, it is of interest in pharmacological research for potential therapeutic applications in pain management and treatment of mood disorders. As a synthetic or naturally occurring peptide, it is typically studied in the context of neurobiology and pharmacology.
