| phenol | <chemistry> 1. A white or pinkish crystalline substance, C6H5OH, produced by the destructive distillation of many organic bodies, as wood, coal, etc, and obtained from the heavy oil from coal tar. It has a peculiar odour, somewhat resembling creosote, which is a complex mixture of phenol derivatives. It is of the type of alcohols, and is called also phenyl alcohol, but has acid properties, and hence is popularly called carbolic acid, and was formerly called phenic acid. It is a powerful caustic poison, and in dilute solution has been used as an antiseptic. 2. Any one of the series of hydroxyl derivatives of which phenol proper is the type. <chemistry> Glacial phenol, any one of a series of compounds having both phenol and aldehyde properties. Phenol phthalein. See Phthalein. Origin: Gr. To show + -ol: cf. F. Phenol. Source: Websters Dictionary (01 Mar 1998) |

| phenol coefficient | A figure expressing the disinfecting power of any substance; it is obtained by dividing the figure indicating the degree of dilution of the disinfectant that kills a microorganism in a given time by that indicating the degree of dilution of phenol which kills the organism in the same space of time under similar conditions. Synonym: hygienic laboratory coefficient, phenol coefficient. (05 Mar 2000) |
| phenol glucuronosyltransferase | <enzyme> Also catalyses the glucuronidation of 1-naphthol, 4-methylumbelliferone, 4-nitrophenol and related cpds; encoded by ugt1 complex Registry number: EC 2.4.1.- Synonym: phenol gcstransferase, phenol udp-glucuronosyltransferase, ugt1a1, rat, 1-naphthol udp-glucuronosyltransferase (26 Jun 1999) |
| phenol oxidase | <enzyme> An enzyme oxidizing benzenediols to semiquinones with O2. Synonym: monophenol monooxygenase, phenol oxidase, phenolase, polyphenol oxidase, urushiol oxidase. (05 Mar 2000) |
| phenol red | <chemical> 4,4'-(3h-2,1-benzoxathiol-3-ylidene)bisphenol s,s-dioxide. Red dye, pH indicator, and diagnostic aid for determination of renal function. It is used also for studies of the gastrointestinal and other systems. Pharmacological action: indicators and reagents, phthalein dyes. Chemical name: Phenol, 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis-, S,S-dioxide (12 Dec 1998) |
| tyrosine phenol-lyase | <enzyme> An enzyme that catalyses the cleavage of tyrosine to phenol, pyruvate, and ammonia. It is a pyridoxal phosphate protein. The enzyme also forms pyruvate from d-tyrosine, l-cysteine, s-methyl-l-cysteine, l-serine, and d-serine, although at a slower rate. Chemical name: L-Tyrosine phenol-lyase (deaminating) Registry number: EC 4.1.99.2 (12 Dec 1998) |
| 2,6-diisopropyl phenol | <chemical> 2,6-bis(1-methylethyl)phenol. An intravenous anaesthetic and a sedative for patients in the intensive care unit or under regional anaesthesia. Induction of anaesthesia is rapid and maintenance can be achieved by either continuous infusion or intermittent bolus injection. Recovery from propofol is rapid and the patient is clear-headed with almost no hangover effect or nausea following administration. Pharmacological action: anaesthetics, intravenous, free radical scavengers, sedatives, nonbarbiturate. Chemical name: Phenol, 2,6-bis(1-methylethyl)- (12 Dec 1998) |
| amino acid reagent | A reagent used in the identification and quantification of amino acids. (05 Mar 2000) |
| Benedict-Hopkins-Cole reagent | <chemistry> Magnesium glyoxalate, made from a mixture of oxalic acid and magnesium, used for testing proteins for the presence of tryptophan. (12 Aug 2000) |
| biuret reagent | An alkaline solution of copper sulfate. (05 Mar 2000) |
| Mandelin's reagent | A solution of ammonium vanadate in sulfuric acid, used in colour tests for alkaloids. (05 Mar 2000) |
| reagent | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| reagent kits, diagnostic | Commercially prepared reagent sets, with accessory devices, containing all of the major components and literature necessary to perform one or more designated diagnostic tests or procedures. They may be for laboratory or personal use. (12 Dec 1998) |
| reagent strips | Narrow pieces of material impregnated or covered with a substance used to produce a chemical reaction. The strips are used in detecting, measuring, producing, etc., other substances. (12 Dec 1998) |
| Marme's reagent | A solution of potassium iodide and cadmium iodide used in testing for alkaloids. (05 Mar 2000) |
