| carbon-14 | A beta-emitter with a half-life of 5715 years, widely used as a tracer in studying various aspects of metabolism; naturally occurring 14C, arising from cosmic ray bombardment, is used to date relics containing natural carbonaceous materials. (05 Mar 2000) |

| carbon bisulfide | <chemical> Carbon disulfide (cs2). A colourless, flammable, poisonous liquid, cs2. It is used as a solvent, and is a counterirritant and has local anaesthetic properties but is not used as such. It is highly toxic with pronounced CNS, haematologic, and dermatologic effects. Chemical name: Carbon disulfide (12 Dec 1998) |
| carbon compounds, inorganic | Inorganic compounds that contain carbon as an integral part of the molecule but are not derived from hydrocarbons. (12 Dec 1998) |
| carbon dichloride | An anthelmintic against hookworm and other nematodes. Synonym: carbon dichloride, ethylene tetrachloride, tetrachloroethylene. (05 Mar 2000) |
| carbon disulfide | <chemical> Carbon disulfide (cs2). A colourless, flammable, poisonous liquid, cs2. It is used as a solvent, and is a counterirritant and has local anaesthetic properties but is not used as such. It is highly toxic with pronounced CNS, haematologic, and dermatologic effects. Chemical name: Carbon disulfide (12 Dec 1998) |
| carbon disulfide poisoning | Acute or chronic intoxication by CS2, an industrial condition encountered among rubber workers and makers of artificial silk (rayon) by the viscose process; characterised by insomnia, listlessness, and irritability, followed by paralyses, impaired vision, peptic ulcer, and psychoses. (05 Mar 2000) |
| carbon isotopes | Stable carbon atoms that have the same atomic number as the element carbon, but differ in atomic weight. C-13 is a stable carbon isotope. (12 Dec 1998) |
| carbon monoxide | <chemical> An organic byproduct of combustion, tasteless, odourless gas that competes with oxygen binding sites on the haemoglobin molecule. Early symptoms of carbon monoxide exposure include headache and nausea. Advanced exposure results in coma, cardiovascular collapse and death. (27 Sep 1997) |
| carbon monoxide dehydrogenase disulfide reductase | <enzyme> Catalyses a reversible exchange of coash with acetyl-CoA in combination with carbon monoxide dehydrogenase (EC 1.2.99.2) Registry number: EC 1.8.- Synonym: co dehydrogenase disulfide reductase, co-dd-reductase (26 Jun 1999) |
| carbon monoxide haemoglobin | <chemical> Chemical name: Haemoglobins, carbonyl- (12 Dec 1998) |
| carbon monoxide-methylene blue oxidoreductase | <enzyme> Molybdenum-containing iron-sulfur flavoprotein from pseudomonas carboxydovorans; forms carbon dioxide Registry number: EC 1.2.3.- Synonym: cm-mb oxidoreductase, carbon monoxide oxidase (26 Jun 1999) |
| carbon monoxide poisoning | Toxic asphyxiation due to the displacement of oxygen from oxyhemoglobin by carbon monoxide. (12 Dec 1998) |
| carbon-nitrogen ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-nitrogen bond. Registry number: EC 6.3 (12 Dec 1998) |
| carbon-nitrogen ligases with glutamine as amide-n-donor | <enzyme> Enzymes that catalyze the joining of glutamine-derived ammonia and another molecule. The linkage is in the form of a carbon-nitrogen bond. Registry number: EC 6.3.5 (12 Dec 1998) |
| carbon-nitrogen lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-nitrogen bond by means other than hydrolysis or oxidation. Subclasses are the ammonia-lyases, the amidine-lyases, the amine-lyases, and other carbon-nitrogen lyases. Registry number: EC 4.3 (12 Dec 1998) |
