γ-aminobutyric acid, also known as 4-aminobutyric acid, is an amino acid that widely exists in plants, microbes and vertebrates as an important inhibitory neurotransmitter in the central nervous system. In industry, γ-Aminobutyric acid we use is white crystalline powder in appearance and has natural activity. Molecular formula C4H9NO2, molecular weight 103.12, CAS Number 56-12-2, EINECS number 200-258-6. γ-aminobutyric acid usually exists in solutions in the form of negatively charged carboxyl group and positively charged amino aminoamphoteric ions. Due to the mutual electrostatic interaction between amphoteric ions, γ-aminobutyric acid can present both gaseous and solid molecular conformation in solutions. The coexistence of multi-molecular conformation usually occurs, which plays an important role in the physiological function of γ-aminobutyric acid.
γ-aminobutyric acid is a non-protein amino acid with small molecular weight, which is highly safe to use. Besides, it has good water solubility and thermal stability. In the current market, it is often applied in food and beverage industries. γ-aminobutyric acid also has certain physiological effects, which can help us reduce blood pressure and improve sleep quality, etc.
