γ-aminobutyric acid (GAMma-aminobutyric acid) is an amino acid widely found in plants, microorganisms, and vertebrates. It is a very important inhibitory neurotransmitter in the central nervous system. γ-aminobutyric acid is found mainly in the brain and spinal cord, and plays an important role in the hippocampus, cerebral cortex, basal ganglia, thalamus, and cerebellum, regulating many functions in the body.
The common γ-aminobutyric acid in the market is usually a white crystalline powder with certain natural activity, molecular formula C4H9NO2, molecular weight 103.12, CAS number 56-12-2.
γ-aminobutyric acid in solution there are two main properties, respectively in the form of negatively charged carboxyl and positively charged aminoamphoteric ions, due to the electrostatic interaction between amphoteric ions, so that the solution of γ-aminobutyric acid both showed a gaseous molecular conformation, also showed a solid molecular conformation, generally speaking, in the form of coexistence of a variety of molecular conformations, Therefore, gamma-aminobutyric acid can play an important physiological function.
γ-aminobutyric acid is a small molecular weight of non-protein amino acids, and the use of relatively high safety has good water solubility and thermal stability, therefore, γ-aminobutyric acid is often used in food, beverage, medicine, and other fields.
