APPLICATIONS
Aminobutyric acid is a four-carbon carboxylic acid, to which an amino group is attached. There are three structural isomers, alpha, beta, gamma-. Alpha-aminobutyric acid is has an amino group substituted at the alpha, or 1 position on the carbon atom next to the acid group, while gamma-aminobutyric acid (GABA) at the terinal carbon (the gamma, or 4 position). Natural GABA exits in L-form only and can be found in plant and animal tissues. It is formed in the metabolism of L-glutamic acid.  It is the central nervous system postsynaptic inhibitory transmitter in the brain but is also found in several extraneural tissues, including kidney and pancreatic islet beta cells. Gamma- hydroxy butyric acid is an intermediate occurring in metabolism of GABA. There are several hydroxy butyric acid occur at elevated levels in some metabolic disorders.  In biological systems The GABA family products are the parent compounds for a number of psychoactive drugs covering sedation/hypnosis, anxiolysis, anticonvulsant activity, muscle relaxation and anterograde amnesia. Some examples are benzodiazepines, baclofen, bicuculline, barbiturates, picrotoxin, neurosteroids and the general anesthetics.
