| toluene-4-monooxygenase | <enzyme> Enzyme system contains 3 protein components; the reconstituted enzyme system catalyses the oxidation of toluene to p-cresol by an NADPH-dependent monooxygenation reaction in which one atom of molecular oxygen in incorporated into the hydroxyl group cresol Registry number: EC 1.14.13.- (26 Jun 1999) |
| toluenyl | <chemistry> Tolyl. Origin: Toluene + -yl. Source: Websters Dictionary (01 Mar 1998) |
| toluic | <chemistry> Pertaining to, or designating, one of three metameric acids, CH3.C6H4.CO2H, which are related to toluene and analogous to benzoic acids. They are white crystalline substances, and are called respectively orthotoluic acid, metatoluic acid, and paratoluic acid. Source: Websters Dictionary (01 Mar 1998) |
| toluic acid | CH3C6H4COOH; Methylbenzoic acid;an oxidation product of xylene. (05 Mar 2000) |
| toluid | <chemistry> A complex double tolyl and toluidine derivative of glycocoll, obtained as a white crystalline substance. Source: Websters Dictionary (01 Mar 1998) |
| toluidine | <chemistry> Any one of three metameric amido derivatives of toluene analogous to aniline, and called respectively orthtoluidine, metatoluidine, and paratoluidine; especially, the commonest one, or paratoluidine, which is obtained as a white crystalline substance. It is used in the aniline dye industry, and constitutes the essential nucleus or radical of those dyes. Source: Websters Dictionary (01 Mar 1998) |
| toluidine blue | <chemical> A thiazin dye related to methylene blue and Azure A in structure, often used for staining thick resin sections. Typically exhibits metachromasia. (18 Nov 1997) |
| toluidine blue O | A blue basic dye, C15H16N3SCl, used as an antibacterial agent, as a nuclear stain, and to stain metachromatically certain structures (e.g., the granules in mast cells which are believed to contain heparin and cartilage matrix which is rich in chondroitin sulfate), and in electrophoresis to stain RNA, RNase, and mucopolysaccharides; it also antagonises the anticoagulant action of heparin. See: tolonium chloride. (05 Mar 2000) |
