Definition of gamma-aminobutyric acid in English:
gamma-aminobutyric acid
noun-ˈamɪnəʊ--əˌmʌɪnəʊ-ˌɡaməəˌmiːnəʊbjuːˈtɪrɪkˈɡamə-əˌmēnōbyo͞oˈtirik ˈasid
mass nounBiochemistry An amino acid which acts to inhibit the transmission of nerve impulses in the central nervous system.
Chemical formula: H₂NCH₂CH₂CH₂COOH
Example sentencesExamples
- Important neurotransmitters that are created from amino acids include serotonin and gamma-aminobutyric acid.
- Instead, the etiology of the disorder is related to abnormalities of serotonin, norepinephrine, gamma-aminobutyric acid, dopamine, and cholecystokinin.
- Phytosterols, a volatile oil, and amino acids, including gamma-aminobutyric acid and L-canavanine, have been isolated from the root.
- These effects are thought to occur by enhancing the actions of gamma-aminobutyric acid in the central nervous system.
- Hypoxia increases central nervous system levels of specific neuroinhibitors such as endogenous opioids, adenosine, and gamma-aminobutyric acid.
Origin
Early 20th century: gamma indicating the relative position of amino on the third carbon away from the acid group.
