| acetone carboxylase | <enzyme> An ATP-dependent carboxylase Registry number: EC 4.1.1.- (26 Jun 1999) |
|---|---|
| acetone chloroform | <chemical> A colourless to white crystalline compound with a camphoraceous odour and taste. It is a widely used preservative in various pharmaceutical solutions, especially injectables. Also, it is an active ingredient in certain oral sedatives and topical anaesthetics. Pharmacological action: preservatives, pharmaceutical, sedatives, nonbarbiturate. Chemical name: 2-Propanol, 1,1,1-trichloro-2-methyl- (12 Dec 1998) |
| acetone compound | <biochemistry> Any of the three compounds created by acetyl coenzyme A (acetoacetate, hydroxybutyrate, and acetone) which are water-soluble cellular fuels normally exported by the liver. They can build up in the blood and body tissues because of starvation, untreated diabetes mellitus, or other disorders that interfere with carbohydrate metabolism. The body rids itself of ketones mainly through urine, but it rids itself of acetone through the lungs, which gives the breath a characteristic fruity odour. If ketones build up in the body long enough, they cause serious illness and coma (see ketoacidosis.) (09 Oct 1997) |
| acetone fixative | Acetone used at low temperatures to fix enzymes, particularly phosphatases; it removes fat and glycogen. (05 Mar 2000) |
| acetone monooxygenase | <enzyme> Converts acetone to acetol and acetol to methylglyoxal Registry number: EC 1.14.13.- Synonym: acetol monooxygenase (26 Jun 1999) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| acetone-butanol fermentation | <biochemistry, microbiology> The formation of acetone and butanol through the fermentation of glucose by Clostridium acetobutylicum. However, most industrial plants make acetone and butanol through synthetic processes that use petrochemicals. (06 May 1997) |
| acetone-insoluble antigen | A diphosphatidyl glycerol that is found in the membrane of Treponema pallidum and is the antigen detected by the Wasserman test for syphilis. (18 Nov 1997) |
| acetonitrile | CH3CN; Methyl cyanide;a colourless fluid of aromatic odour, soluble in water and alcohol. (05 Mar 2000) |
| acetonitriles | Compounds in which a methyl group is attached to the cyano moiety. (12 Dec 1998) |
| acetonuria | Excretion in the urine of large amounts of acetone, an indication of incomplete oxidation of large amounts of lipids; commonly occurs in diabetic acidosis. Origin: acetone + G. Ouron, urine (05 Mar 2000) |
| acetophenazine maleate | 2-Acetyl-103-[4-(2-hydroxyethyl)piperazinyl]propylphenothiazine dimaleate;a phenothiazine tranquilliser. (05 Mar 2000) |
| acetophenetidin | <chemical> A non-prostaglandin synthase inhibitor. It was utilised extensively in a wide variety of analgesic mixtures, but its causal role in analgesic-abuse nephropathy led to its withdrawal from the market. Chemical name: Acetamide, N-(4-ethoxyphenyl)- (12 Dec 1998) |
