γ aminobutyricacid(GABA)γ -aminobutyric acid, chemical name: 4 aminobutyricacid; Aliases: gamma-aminobutyric acid, aminobutyric acid, piperidinic acid, widely distributed in animals and plants. Gamma-aminobutyric acid (GAMMA-AMinobutyric acid) is found in seeds, roots and tissue fluids of plants such as bean, ginseng and Chinese herbal medicine. In Chemicalbook animals, GABA almost only exists in the nerve tissue, the content of brain tissue is about 0.1 0.6mg/g tissue, immunological studies show that the highest concentration of the region is the substantia nigra in the brain. γ -aminobutyric acid is an important inhibitory neurotransmitter which has been studied deeply at present. It participates in various metabolic activities and has high physiological activity.

γ -aminobutyric acid (GABA) is a natural active ingredient widely distributed in animals and plants. Gamma-aminobutyric acid (GAMMA-AMinobutyric acid) is found in seeds, roots and tissue fluids of plants such as bean, ginseng and Chinese herbal medicine. In animal Chemicalbook, γ -aminobutyric acid almost only exists in nerve tissue, and the concentration of γ -aminobutyric acid in brain tissue is about 0.1 ~ 0.6mg/g. Immunological studies show that the highest concentration of γ -aminobutyric acid is in the substantia nigra of brain.

1.It is used for biochemical research and medical treatment of various diseases caused by hepatic coma and cerebrovascular disorders.

2.Pharmaceutical intermediates. 4- aminobutyric acid has the effect of lowering blood lipid and is suitable for the treatment and prevention of various types of hepatic coma. Treatment of poliomyelitis, cerebral hemorrhage, and gas poisoning antidote. It is also used in biochemical research and organic synthesis.

3.Can reduce blood ammonia, promote brain metabolism. For the treatment of various types of liver coma, also used for brain death sequela, cerebral arteriosclerosis, head trauma sequela and uremia, gas poisoning caused by coma.

4.The main inhibitory neurotransmitter in the brain; GABAA and GABAB receptor stimulants; Increase Cl− conductivity.
