| potassium cyanide | <chemical> Potassium cyanide (k(cn)). A highly poisonous compound that is an inhibitor of many metabolic processes, but has been shown to be an especially potent inhibitor of haem enzymes and haemproteins. It is used in many industrial processes. Pharmacological action: enzyme inhibitors, poisons. Chemical name: Potassium cyanide (K(CN)) (12 Dec 1998) |

| cadmium | <chemical> An element with atomic symbol cd, atomic number 48, and atomic weight 114. It is a metal and ingestion will lead to cadmium poisoning. Chemical name: Cadmium (12 Dec 1998) |
| cadmium chloride | <chemical> A cadmium halide in the form of colourless crystals, soluble in water, methanol, and ethanol. It is used in photography, in dyeing, and calico printing, and as a solution to precipitate sulfides. Pharmacological action: carcinogens, mutagens, teratogens. Chemical name: Cadmium chloride (CdCl2) (12 Dec 1998) |
| cadmium compounds | Inorganic compounds that contain cadmium as an integral part of the molecule. (12 Dec 1998) |
| cadmium poisoning | Poisoning occurring after exposure to cadmium compounds or fumes. It may cause gastrointestinal syndromes, anaemia, or pneumonitis. (12 Dec 1998) |
| cadmium radioisotopes | Unstable isotopes of cadmium that decay or disintegrate emitting radiation. Cd atoms with atomic weights 103-105, 107, 109, 115, and 117-119 are radioactive cadmium isotopes. (12 Dec 1998) |
| cadmium translocating ATPase | <enzyme> Cadmium-efflux atpase; e1,e2-translocating atpase is a generic name which includes all cation-transport atpases; do not confuse with lysine decarboxylase cada Registry number: EC 3.6.1.- Synonym: cada atpase, cd-e1,e2-translocating atpase (26 Jun 1999) |
| allyl cyanide | CH2==CHCH2CN; 3-butenenitrile;found in some mustard oils. (05 Mar 2000) |
| ascorbate-cyanide test | A test for glucose-6-phosphate-deficient red blood cells; blood is incubated with sodium cyanide and ascorbate; the hydrogen peroxide generated is free to oxidise haemoglobin to methemoglobin, since cyanide inhibits catalase; a brown colour is produced more rapidly in glucose 6-phosphate-deficient cells. (05 Mar 2000) |
| carbonyl cyanide m-chlorophenyl hydrazone | <chemical> A proton ionophore. It is commonly used as an uncoupling agent and inhibitor of photosynthesis because of its effects on mitochondrial and chloroplast membranes. Pharmacological action: uncoupling agents, ionophores. Chemical name: Propanedinitrile, ((3-chlorophenyl)hydrazono)- (12 Dec 1998) |
| carbonyl cyanide p-trifluoromethoxyphenylhydrazone | <chemical> A proton ionophore that is commonly used as an uncoupling agent in biochemical studies. Pharmacological action: ionophores, uncoupling agents. Chemical name: Propanedinitrile, ((4-(trifluoromethoxy)phenyl)hydrazono)- (12 Dec 1998) |
| cyanide | 1. The radical -CN or ion (CN)-. The ion is extremely poisonous, forming hydrocyanic acid in water; inhibits respiratory proteins. 2. A salt of HCN or a cyano-containing molecule. (05 Mar 2000) |
| cyanide dihydratase | <enzyme> From bacillus pumilus c1; catalyses the conversion of cyanide to formate and ammonia Registry number: EC 3.5.5.- (26 Jun 1999) |
| cyanide hydratase | <enzyme> Converts hcn to formamide in the fungus gloeocercospora sorghi Registry number: EC 4.2.1.66 Synonym: formamide hydro-lyase (26 Jun 1999) |
| cyanide methemoglobin | A relatively nontoxic compound of cyanide with methemoglobin, which is formed when methylene blue is administered in cases of cyanide poisoning. Synonym: cyanide methemoglobin. (05 Mar 2000) |
