| 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) |
