| malonic acid | HOOC-CH2-COOH;a dicarboxylic acid of importance in intermediary metabolism; an inhibitor of succinate dehydrogenase. Synonym: propanedioic acid. (05 Mar 2000) |
|---|---|
| malonyl-CoA-anthranilic acid N-malonyltransferase | <enzyme> From peanuts Registry number: EC 2.3.1.- Synonym: anthranilic acid n-malonyltransferase, aa malonyltransferase, malonyl-coenzyme a-anthranilic acid n-malonyltransferase (26 Jun 1999) |
| paraaminobenzoic acid | A factor in the vitamin B complex, a part of all folic acids and required for its formation; neutralises the bacteriostatic effects of the sulfonamides since it furnishes an essential growth factor for bacteria, the utilization with which the sulfonamides interfere; used as an ultraviolet screen in lotions and creams. Synonym: paraaminobenzoic acid, vitamin Bx. Acronym: PABA (05 Mar 2000) |
| parabanic acid | The cyclic (end-to-end) amide anhydride of oxaluric acid; an oxidation product of uric acid. Synonym: oxalourea, parabanic acid. (05 Mar 2000) |
| mandelic acid | C6H5CHOHCOOH;a urinary antibacterial agent (both bactericidal and bacteriostatic). Synonym: hydroxytoluic acid, phenylglycolic acid. Origin: Ger. Mandel, almond (05 Mar 2000) |
| general acid-base catalysis | A catalytic reaction that involves the tranfer of a proton to or from anon-water molecule. (09 Oct 1997) |
| mannuronic acid | Uronic acid derived from the oxidation of mannose. (05 Mar 2000) |
| receptors, amino acid | Cell surface proteins that bind amino acids and trigger changes which influence the behaviour of cells. Glutamate receptors are the most common receptors for fast excitatory synaptic transmission in the vertebrate central nervous system, and gaba and glycine receptors are the most common receptors for fast inhibition. (12 Dec 1998) |
| receptors, kainic acid | Cell surface proteins that bind glutamate and directly gate ion channels. Kainic acid receptors were originally discriminated from other glutamate receptors by their affinity for the agonist kainic acid. Activation of kainic acid receptors is generally excitatory to cells. Subtypes have been cloned, and for some the traditional distinction from ampa receptors may not apply. (12 Dec 1998) |
| veratric acid | C9H10O4; 3,4-Dimethoxybenzoic acid;obtained by methylation and subsequent oxidation of protocatechuic acid; present in the seeds of Schoenocaulon officinale (Sabadilla officinarum). (05 Mar 2000) |
| gentisic acid | 2,5-Dihydroxybenzoic acid; 5-hydroxysalicylic acid;this compound is chemically related to salicylate and aspirin (acetylsalicylate) and shares with the latter agent analgesic and anti-inflammatory properties. (05 Mar 2000) |
| receptors, retinoic acid | Proteins in the nucleus or cytoplasm that specifically bind retinoic acid or retinol and trigger changes in the behaviour of cells. Retinoic acid receptors, like steroid receptors, are ligand-activated transcription regulators. Several types have been recognised. (12 Dec 1998) |
| Gerhardt's test for acetoacetic acid | In fresh urine a red colour develops upon addition of FeCl3; no colour develops if the urine has first been boiled; this test has low specificity and sensitivity. Synonym: Gerhardt's reaction. (05 Mar 2000) |
| casamino acid | <biochemistry> The group of amino acids which results when casein, a protein found in milk, is broken down by enzymes. (09 Oct 1997) |
| gibberellic acid | <plant biology> Diterpenoid compounds with gibberellin activity in plants. at least 70 related gibberellic acids have been described and designated as a series GA1, GA2 etc. (17 Dec 1997) |
