| atractylic acid | A highly poisonous steroid glycoside from Atractylis gummifera L. (Compositae), having a strychnine-like action that produces convulsions of a hypoglycaemic nature; the aglycon, atractyliginin, is combined with glucose and isovaleric acid, and is the toxic principle. Atractylic acid interferes with oxidative reactions, the citric acid cycle, and nerve conduction. (05 Mar 2000) |

| aureolic acid | An antibiotic produced by Streptomyces argillaceus and S. Tanashiensis; possesses antineoplastic activity. Synonym: aureolic acid, mitramycin. (05 Mar 2000) |
| aurintricarboxylic acid | <chemical> 5-((3-carboxy-4-hydroxyphenyl)(3-carboxy-4-oxo-2,5-cyclohexadien-1-ylidene)methyl)-2-hydroxybenzoic acid. A dye which inhibits protein biosynthesis at the initial stages. The ammonium salt (aluminon) is a reagent for the colourimetric estimation of aluminum in water, foods, and tissues. Chemical name: Benzoic acid, 5-((3-carboxy-4-hydroxyphenyl)(3-carboxy-4-oxo-2,5-cyclohexadien-1-ylidene)methyl)-2-hydroxy- (12 Dec 1998) |
| azetidinecarboxylic acid | <chemical> 2-azetidinecarboxylic acid. A proline analog. Acts as a stoichiometric replacement of proline causing the production of abnormal proteins having impaired biological activity. Chemical name: 2-Azetidinecarboxylic acid (12 Dec 1998) |
