| alpha-amanitin | <drug> A highly toxic, heat-stable bicyclic oligopeptide derived from the Amanita phalloides mushroom. It inhibits transcription by interfering with the function of certain RNA polymerases. (14 Aug 2000) |
| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |
| alpha-amino acid | Typically, an amino acid of the general formula R-CHNH2-COOH (i.e., the NH2 in the a position); the l forms of these are the hydrolysis products of proteins. In rarer usages, this class of molecules also includes alpha-amino phosphoric acids and alpha-aminosulfonic acids. (05 Mar 2000) |
| alpha-amino acid esterase | <enzyme> Converts alpha-amino acid esters and water to alpha-amino acids and alcohol Registry number: EC 3.1.1.43 Synonym: alpha-amino acid ester hydrolase (26 Jun 1999) |

| alpha-amino-beta-ketoadipic acid | 2-Amino-3-oxo-1,6-hexanedioic acid;an intermediate of porphobilinogen synthesis formed by d-aminolevulinic acid synthase from succinyl-CoA and glycine; it rapidly decarboxylates to d-aminolevulinic acid. (05 Mar 2000) |
| alpha-aminoglutaric acid | <amino acid> One of the 20 _ amino acids commonly found in proteins. Plays a central role in amino acid metabolism, acting as precursor of glutamine, proline and arginine. Also acts as amino group donor in synthesis by transamination of alanine from pyruvate and aspartic acid from oxaloacetate. Glutamate is also a neurotransmitter, the product of its decarboxylation is the inhibitory neurotransmitter amino butyrate (GABA). (18 Nov 1997) |
| alpha-aminoisobutyric acid | 2-amino-2-methylpropionic acid;a synthetic amino acid useful in the study of amino acid transport across cell membranes and in the study of cytokine effects; it is not metabolised by the cell. (05 Mar 2000) |
