| carbon-phosphorus lyase | <enzyme> Found in bacteria which utilise alkyl and phenylphosphonic acids Registry number: EC 4.99.- Synonym: c-p lyase, carbon-phosphorus cleavage enzyme (26 Jun 1999) |
|---|---|
| carbon-sulfur ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-sulfur bond. Registry number: EC 6.2 (12 Dec 1998) |
| carbon-sulfur lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-sulfur bond by means other than hydrolysis or oxidation. Registry number: EC 4.4 (12 Dec 1998) |
| carbonate | 1. A salt of carbonic acid. 2. The ion CO3=. (05 Mar 2000) |
| carbonate dehydratase | <enzyme> A zinc-containing enzyme of erythrocytes with molecular weight of 30 kD. It is among the most active of known enzymes and catalyses the reversible hydration of carbon dioxide, which is significant in the transport of co2 from the tissues to the lungs. The enzyme is inhibited by acetazolamide. Chemical name: Carbonate hydro-lyase Registry number: EC 4.2.1.1 (12 Dec 1998) |
| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |
| carbonate hydro-lyase | carbonic anhydrase |
| carbonated beverages | Drinkable liquids combined with or impregnated with carbon dioxide. (12 Dec 1998) |
| carbonated water | Carbonic water, water that contains a considerable amount of carbonic acid in solution. (05 Mar 2000) |
| carbonates | Salts or ions of the theoretical carbonic acid, containing the radical co2(3-). Carbonates are readily decomposed by acids. The carbonates of the alkali metals are water-soluble; all others are insoluble. (12 Dec 1998) |
| carbonic | Relating to carbon. See also under carbonate. (05 Mar 2000) |
| carbonic acid | <chemical> Carbonic acid (h2c03). The hypothetical acid of carbon dioxide and water. It exists only in the form of its salts (carbonates), acid salts (hydrogen carbonates), amines (carbamic acid), and acid chlorides (carbonyl chloride). Chemical name: Carbonic acid (12 Dec 1998) |
| carbonic acid gas | <biochemistry, physiology> A metabolic byproduct of carbohydrate metabolism. Carbon Dioxide collects in the tissues, is cleared by the blood (via the veins) and removed from the body via the lungs when we exhale air. Abbreviation: CO2 (13 Nov 1997) |
| carbonic acid inhibitor | <pharmacology> A group of diuretic medications which act to inhibit the enzyme carbonic anhydrase to create a metabolic acidosis. Many of these medications are used in the treatment of glaucoma. (27 Sep 1997) |
| carbonic anhydrase II deficiency syndrome | <syndrome> An inherited deficiency of carbonic anhydrase II that results in osteopetrosis and metabolic acidosis. Synonym: osteopetrosis with renal tubular acidosis. (05 Mar 2000) |
