| 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) |
| carbonyl group | A group in which an oxygen atom is double-bonded to a carbon atom: O=C. The carbon atom then has two additional bonds to attach to the rest of the molecule. Organic molecules containing a carbonyl group are a very important, major group of compounds studied in the field of organic chemistry. (09 Oct 1997) |
| pig lung carbonyl reductase | <enzyme> Tetrameric carbonyl reductase; mw 24 kD; properties distinct from monomeric cr; it is mainly distributed in the mitochondria of the pig lung; exhibits very low substrate specificity for aromatic and aliphatic carbonyl compounds and catalyses the oxidation of secondary alcohols and aldehydes; activated 2-5 fold by fatty acids ddbj/embl/genbank d16511 Registry number: EC 1.1.1.- (26 Jun 1999) |

| nickel | 1. <chemistry> A bright silver-white metallic element. It is of the iron group, and is hard, malleable, and ductile. It occurs combined with sulphur in millerite, with arsenic in the mineral niccolite, and with arsenic and sulphur in nickel glance. Symbol Ni. Atomic weight 58.6. On account of its permanence in air and inertness to oxidation, it is used in the smaller coins, for plating iron, brass, etc, for chemical apparatus, and in certain alloys, as german silver. It is magnetic, and is very frequently accompanied by cobalt, both being found in meteoric iron. 2. A small coin made of or containing nickel; especially, a five-cent piece. Nickel silver, an alloy of nickel, copper, and zinc; usually called german silver. Synonym: argentan. Origin: G, fr. Sw. Nickel, abbrev. From Sw. Kopparnickel copper-nickel, a name given in derision, as it was thought to be a base ore of copper. The origin of the second part of the word is uncertain. Cf. Kupfer-nickel, Copper-nickel.
