Metabolite Identification
Common NameN-Methyl-4-aminobutyric acid
Description4-(methylamino)butyric acid, also known as gamma-N-methylaminobutyrate or 4-methylamino-buttersaeure, belongs to the class of organic compounds known as gamma amino acids and derivatives. These are amino acids having a (-NH2) group attached to the gamma carbon atom. A gamma-amino acid comprising that is GABA in which one of the hydrogens attached to the nitrogen is replaced by a methyl group. 4-(methylamino)butyric acid is a very strong basic compound (based on its pKa).
