| glyoxylic acid | OHC-COOH;produced by the action of glycine dehydrogenases upon glycine or sarcosine, or from allantoic acid by allantoicase or via alanine:glyoxylate aminotransferase. Synonym: oxoacetic acid. (05 Mar 2000) |
|---|---|
| glyoxylic acid cycle | A catabolic cycle in plants and microorganisms like that of the tricarboxylic acid cycle in animals; its key reaction is the condensation of acetyl-CoA with glyoxylic acid to malic acid (analogous to the condensation of acetyl-CoA and oxaloacetic acid to form citric acid in the tricarboxylic acid cycle). Synonym: Krebs-Kornberg cycle. (05 Mar 2000) |
| penicilloic acid | Alkali and bacterial degradation product of a penicillin, resulting from hydrolysis of the 1,7 bond. (05 Mar 2000) |
| cerebronic acid | 2-Hydroxylignoceric acid, 2-hydroxytetraeicosanoic acid; CH3-(CH2)21-CHOH-COOH. A constituent of phrenosin (cerebron) and other glycolipids. Synonym: phrenosinic acid. (05 Mar 2000) |
| melissic acid | Found in waxes. Origin: G. Melissa, bee + -ic (05 Mar 2000) |
| pentanoic acid | CH3(CH2)3COOH;normal aliphatic acid; distilled from valerian; some of its salts are used in medicine; found in human colon. Synonym: pentanoic acid. (05 Mar 2000) |
| cerotinic acid | CH3-(CH2)24 -COOH; n-hexacosanoic acid;a long-chain fatty acid found in natural waxes and in certain lipids. (05 Mar 2000) |
| pentetic acid | A pentaacetic acid triamine with affinity for heavy metals; used as the calcium sodium chelate in the treatment of iron-storage disease and poisoning from heavy metals and radioactive metals. See: ethylenediaminetetraacetic acid. (05 Mar 2000) |
| retinoic acid | <biochemistry> The aldehyde (retinal) has long been known to be involved in photoreception, but retinoic acid has other roles. There are cytoplasmic retinoic acid binding proteins and retinoic acid response elements that regulate gene transcription. Retinoic acid is thought to be a morphogen in chick limb bud development and in early development of the chick that probably accounts for its potent teratogenic action. Synonym: vitamin A. (03 Jul 1999) |
| retinoic acid 4-hydroxylase | <enzyme> Catalyses the hydroxylation of all-trans retinoic acid to 4-hydroxyretinoic acid Registry number: EC 1.14.- Synonym: ra-4-hydroxylase, cytochrome p450 4-hydroxylase, cyp450 4-hydroxylase (26 Jun 1999) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Gomori's non-specific acid phosphatase stain | <technique> A method in which formalin-fixed frozen sections are incubated in a substrate containing sodium beta-glycerophosphate and lead nitrate at pH 5.0; the insoluble lead phosphate produced is treated with ammonium sulfide to give a black lead sulfide. (05 Mar 2000) |
| peracetic acid | <chemical> Ethaneperoxoic acid. A liquid that functions as a strong oxidizing agent. It has an acrid odour and is used as a disinfectant. Pharmacological action: disinfectants. Chemical name: Ethaneperoxoic acid (12 Dec 1998) |
| cevitamic acid | <biochemistry> A requisite in the diet of man and guinea pigs. May act as a reducing agent in enzymic reactions, particularly those catalysed by hydroxylases. Synonym: Vitamin C. (18 Nov 1997) |
| perchloric acid | <chemical> An oxidizing agent that is used in analytical chemistry for separation of potassium from sodium. Chemical name: Perchloric acid (12 Dec 1998) |

| acid |
A substance which dissolves in water and releases hydrogen ions (H +). Acids cause irritation, bums, or more serious damage to tissue, depending on the strength of the acid, which is measured by pH (see pH).
