| dihematoporphyrin ether | <chemical> The purified component of haematoporphyrin derivative, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (haematoporphyrin photoradiation) to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of photodynamic therapy in the united states. Pharmacological action: antineoplastic agent, antiviral agents, dermatologic agents. Chemical name: 21H,23H-Porphine-2,18-dipropanoic acid, 7-(1-(1-(8,12-bis(2-carboxyethyl)-17-(1-hydroxyethyl)-3,7,13,18-tetramethyl-21H,23H-porphin-2-yl)ethoxy)ethyl)-12-(1-hydroxyethyl)-3,8,13,17-tetramethyl- (12 Dec 1998) |
| diphenyl ether hydroxylase | <enzyme> Uses NADPH Registry number: EC 1.14.- (26 Jun 1999) |
| divinyl ether | O(CH==CH2)2;a volatile liquid, the vapor of which produces rapid induction of general anaesthesia; prolonged administration is associated with adverse side effects on the liver and central nervous system; an obsolete agent. Synonym: vinyl ether. (05 Mar 2000) |
| divinyl ether synthase | <enzyme> Catalyses conversion of hydroperoxides to divinyl ethers; isolated from garlic bulbs allium sativum; preferentially acts sterospecifically on the (s) enantomer of 13-hpod ((9z,11e,13s)-13-hydroperoxy-9,11-octadecadienoic acid Registry number: EC 1.- (26 Jun 1999) |
| ether | 1. <physics> A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether. 2. Supposed matter above the air; the air itself. 3. <chemistry> A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odour, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an anaesthetic. Called also ethyl oxide. Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether. <chemistry> Complex ether, Mixed ether, a condensing engine like a steam engine, but operated by the vapor of ether instead of by steam. Origin: Written also aether. Source: Websters Dictionary (01 Mar 1998) |
| ether convulsion | A convulsion occasionally associated with divinyl and diethyl ether anaesthesia. (05 Mar 2000) |
| ether, ethyl | <chemical> 1,1'-oxybisethane. A mobile, very volatile, highly flammable liquid used as an inhalation anaesthetic and as a solvent for waxes, fats, oils, perfumes, alkaloids, and gums. It is mildly irritating to skin and mucous membranes. Pharmacological action: anaesthetics, inhalation, solvents. Chemical name: Ethane, 1,1'-oxybis- (12 Dec 1998) |
| ether test | An obsolete test to determine arm-to-lung circulation time; diluted ether is injected intravenously and the end point taken when the subject coughs or tastes ether or the observer smells ether on the subject's breath. (05 Mar 2000) |
| ethyl ether | CH3CH2OCH2CH3;a flammable, volatile organic solvent used in extraction procedures; formerly widely used as an inhalation anaesthetic; shortcomings include: irritating vapor, slow onset and prolonged recovery phase, explosion hazard.

| acetyl | <biochemistry, chemistry> This is the radical of acetic acid, it contains a carbonyl and a methyl group that is single-bonded to the carbon, an oxygen is single-bonded to the carbon, and the carbon has two other bonds to the rest of the molecule. (09 Oct 1997) |
| acetyl-activating enzyme | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
| acetyl chloride | CH3COCl;a colourless liquid used as a reagent; also corrosive, causing severe burns because of hydrolysis to HCl. (05 Mar 2000) |
| acetyl-CoA | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
