| benzene | <chemistry> A volatile, very inflammable liquid, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum. The Benzene nucleus or Benzene ring, is a closed chain or ring, consisting of six carbon atoms, each with one hydrogen atom attached, regarded as the type from which the aromatic compounds are derived. Structure: C6H6 Origin: From Benzoin. (06 Aug 1998) |
|---|---|
| benzene 1,2-dioxygenase | <enzyme> Converts benzene into cis-benzene glycol; consists of a flavoprotein reductase, reductase(bed), and a ferredoxin, ferredoxin(bed), which transfers electrons from NADH to an iron-sulfur protein, isp(bed), which acts as a dioxygenase Registry number: EC 1.14.12.3 Synonym: benzene hydroxylase (26 Jun 1999) |
| benzene mono-oxygenase | <enzyme> Cytochrome p-450-dependent; forms benzene oxide Registry number: EC 1.13.12.- (26 Jun 1999) |
| benzene nucleus | The six conjugated carbon atoms of the benzene ring. (05 Mar 2000) |
| benzene ring | The closed-chain arrangement of the carbon and hydrogen atoms in the benzene molecule. See: cyclic compound. (05 Mar 2000) |
| gamma benzene hexachloride | <chemical> One of the purified isomers of hexachlorobenzene which is used as a scabicide and pediculicide applied topically to the skin in various lotions, creams, and shampoos; gamma benzene hexachloride can be absorbed through the skin. Resembles DDT in its actions but is less persistent. Incorrect name for 1,2,3,4,5,6-hexachlorocyclohexane (lindane). Synonym: hexachlorocyclohexane. Acronym: GBH (05 Mar 2000) |
| 1,4-bis(5-phenyloxazol-2-yl)benzene | A liquid scintillation agent used in radioisotope measurement. (05 Mar 2000) |
| active methyl | A methyl group attached to a quaternary ammonium ion or a tertiary sulfonium ion that can take part in transmethylation reactions; e.g., methyl groups in choline and in S-adenosyl-l-methionine, which are thus methyl donors. (05 Mar 2000) |
| aklanonic acid methyl ester cyclase | <enzyme> Catalyses the formation of aklaviketone from aklanonic acid methyl ester; involved in daunomycin biosynthesis; see also daunorubicin-doxorubicin polyketide synthase Registry number: EC 5.- Synonym: aame cyclase, daud protein, daud gene product, dnrd protein, dnrd gene product (26 Jun 1999) |
| alpha-(4-O-methyl)-D-glucuronidase | <enzyme> Removes 4-o-methyl-glucopyranosyl uronic acid residues from the 2-position of fungal cell wall xylans Registry number: EC 3.2.1.- Synonym: 4-o-methyl-glucuronidase (26 Jun 1999) |
| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |
| alpha methyl dopa | <drug> An antihypertensive drug, preferred in pregnant patients. (18 Nov 1997) |
| angular methyl | A methyl group attached to carbon 10 (between rings A and B) or to carbon 13 (between rings C and D) of the steroid nucleus. (05 Mar 2000) |
| bevonium methyl sulfate | 2-(hydroxymethyl)-1,1-dimethylpiperidinium methyl sulfate benzylate;an anticholinergic agent. Synonym: pyribenzyl methyl sulfate. (05 Mar 2000) |
| Mann's methyl blue-eosin stain | <technique> A stain useful for anterior pituitary and viral inclusion bodies; a mixture of the two dyes stains alpha cell granules red, beta cell granules dark blue, chromophobes gray to pink, colloid red, erythrocytes orange-red, and collagen fibres blue; this method is also useful for enterochromaffin, goblet, Paneth, and pancreatic islet cells; Negri bodies appear red while their nuclei and central granules are blue.
