| 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. Synonym: ethyl ether, ethyl oxide, sulfuric ether. (05 Mar 2000) |
