Gamma-aminobutyric acid (γ-aminobutyric acid) is an amino acid widely distributed in plants, microorganisms and vertebrates. It is an important inhibitory neurotransmitter in central nervous system.
In the market, our common γ-aminobutyric acid is a white crystalline powder, with natural activity, molecular formula C4H9NO2, molecular weight 103.12, CAS No.56-12-2, EINECS No.200-258-6. γ-aminobutyric acid in the solution usually exists in two forms, respectively with negatively charged carboxyl group and positively charged amino aminoamphoteric ions, due to the electrostatic interaction between the amphoteric ions, γ-aminobutyric acid can present in the solution of gaseous molecular conformation and solid molecular conformation, mainly the common existence of multi-molecule conformation, This plays an important role in the physiological function of γ-aminobutyric acid.
γ-aminobutyric acid is a small molecular weight non-protein amino acid, high safety to use, and has good water solubility and thermal stability, he is often used in food, beverage and other industries, in addition, γ-aminobutyric acid has a physiological effect on reducing blood pressure, improve sleep quality can play a certain role.
