γ-Aminobutyric acid is a widely exist in plants, microbes and amino acids in vertebrates, central nervous system is also very important inhibitory neurotransmitter, γ-aminobutyric acid is mainly exist in the brain, spinal cord, but in the human body, the cerebral cortex, hippocampus, thalamus, basal ganglia play an important role in the cerebellum, can also regulate the body’s functions.
γ-Aminobutyric acid sold on the market, usually white crystal powder appearance, has a certain natural activity, molecular formula C4H9NO2, molecular weight 103.12, CAS number 56-12-2.
γ-Aminobutyric acid in solution mainly negatively charged carboxyl and positively charged amino zwitterionic form, due to the electrostatic interactions between zwitterionic, this will make the solution of the gamma-aminobutyric acid not only present a gaseous molecular conformation, also can present a solid conformation, usually in multiple conformation coexist, therefore, γ-aminobutyric acid can perform important physiological functions.
γ-Aminobutyric acid as a small molecular weight of non-protein amino acids, safe to use, with good water solubility and thermal stability, therefore, γ-aminobutyric acid is often used in food, beverage, medicine and other fields.
