γ-Glutamylmethylamide (gamma-glutamylmethylamide, abbrev. GMA, synonyms N-methyl-L-glutamine, metheanine) is an amino acid analog of the proteinogenic amino acids L-glutamic acid and L-glutamine, found primarily in plant and fungal species; simply speaking, it is L-glutamine methylated on the amide nitrogen.
