| benzalkonium chloride | A mixture of alkylbenzyldimethylammonium chlorides in which the alkyls are long-chain compounds (C8 to C18); a surface-active germicide for many pathogenic nonsporulating bacteria and fungi. Aqueous solutions of this agent have a low surface tension, and possess detergent, keratolytic, and emulsifying properties that aid the penetration and wetting of tissue surfaces. (05 Mar 2000) |
| benzalkonium compounds | <chemical> A mixture of alkylbenzyldimethylammonium compounds. It is a bactericidal quaternary ammonium detergent used topically in medicaments, deodorants, mouthwashes, as a surgical antiseptic, and as a as preservative and emulsifier in drugs and cosmetics. Pharmacological action: anti-infective agents, local, detergents, preservatives, pharmaceutical. (12 Dec 1998) |
| benzamide | <chemistry> A transparent crystalline substance, obtained by the action of ammonia upon chloride of benzoyl, as also by several other reactions with benzoyl compounds. Structure: C6H5.CO.NH2 Origin: Benzoin + amide. (06 Aug 1998) |
| benzamidines | Amidines substituted with a benzene group. Benzamidine and its derivatives are known as peptidase inhibitors. (12 Dec 1998) |

Pharmacological action: uricosuric agents. Chemical name: Methanone, (3,5-dibromo-4-hydroxyphenyl)(2-ethyl-3-benzofuranyl)- (12 Dec 1998) |
| 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) |
