| toxic unit | A unit formerly synonymous with minimal lethal dose but which, because of the instability of toxins, is now measured in terms of the quantity of standard antitoxin with which the toxin combines. See: L doses, minimal lethal dose. Synonym: toxin unit. (05 Mar 2000) |

| epidermal necrolysis, toxic | An exfoliative disease of skin seen primarily in adults and characterised by flaccid bullae and spreading erythema so that the skin has the appearance of being scalded. It results primarily from a toxic reaction to various drugs, but occasionally occurs as a result of infection, neoplastic conditions, or other exposure. (12 Dec 1998) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
| anomeric carbon | The reducing carbon of a sugar; C-1 of an aldose, C-2 of a 2-ketose. (05 Mar 2000) |
| arteriovenous carbon dioxide difference | <physiology> The difference in carbon dioxide content (in ml per 100 ml blood) between arterial and venous blood. (05 Mar 2000) |
| carbon | <chemistry, element> Sixth element (Z=6) in the periodic table, has 6 protons, often described as the basis of life on earth because of its chemical properties, has potential for use with silicon as a low-activation structural material for fusion reactors, in the form silicon carbide. Carbon tiles are often used in plasma-facing components because its low Z makes carbon a relatively nice impurity. It is also useful as a neutron moderator. See: low-activation materials, plasma-facing components. Abbreviation: C (13 Nov 1997) |
| carbon-11 | A cyclotron-produced, positron-emitting radioisotope of carbon with a half-life of 20.3 minutes; used in positron-emitting tomography. (05 Mar 2000) |
| carbon-12 | The standard of atomic mass, 98.90% of natural carbon. (05 Mar 2000) |
| carbon-13 | A stable natural isotope, 1.1% of natural carbon. (05 Mar 2000) |
| 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 dioxide | <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) |
| carbon dioxide acidosis | <biochemistry> A metabolic derangement of acid-base balance where the blood pH is abnormally low. Causes include haemorrhagic shock, cardiogenic shock, severe dehydration, sepsis, toxic ingestion (for example isopropyl alcohol, methanol), alcoholic ketoacidosis, lactic acidosis, renal failure and diabetic ketoacidosis. Respiratory acidosis will occur if the lungs are not ventilating properly resulting in an excess of carbon dioxide in the body. (25 Jun 1999) |
