4-Aminobutyric acid Usage And Synthesis
Chemical PropertiesWhite microcrystalline powder
UsesAn important inhibitory neurotransmitter. The foods contain γ-aminobutyric acid (GABA) at an amount that shows immediate effect of suppressing autonomic nerve activity related to blood pressure increase. Reacts with isothiocyanates to produce thioureas which have antifungal activity.
DefinitionAn unusual amino acid having the fol- lowing isomers: α: CH 3 CH 2 CH(NH 2 )COOH. Iso- lated from a bacterium (Corynebacterium diph- theriae). The dl form is a crystalline solid, mp 305C, soluble in water, slightly soluble in alco- hol, insoluble in ether. The l(+) form is solid, mp 270C, sweetish taste, soluble in water. β: CH 2 CH(NH 2 )CH 2 COOH. The dl form is a tasteless solid, mp 190C, water soluble, insoluble in ether and alcohol. The d(?) form decomposes at 220C. γ: (GABA) H 2 N(CH 2 ) 3 COOH. Obtained from bac- teria, yeast, and plant life. Crystalline solid, mp 202C, soluble in water, insoluble in organic sol- vents. Decomposes to pyrrolidone and water on quick heating. This substance is reported to be a neurotransmitter that activates or retards nervous reactions in the cells of the brain, including the sense of pain. All three isomers have been synthesized by various reaction sequences, the first reported in 1880.
Biological ActivityEndogenous inhibitory neurotransmitter.
Purification MethodsCrystallise GABA from aqueous EtOH or MeOH/Et2O. Also crystallise it by dissolving it in the least volume of H2O and adding 5-7 volumes of absolute EtOH. [Sherman Biochemical Preparations 4 91 1955, de Witt Org Synth Coll Vol II 25 1943, Beilstein 4 III 1316, 4 IV 2600.]
