Chemical name: Acetolactate pyruvate-lyase (carboxylating) Registry number: EC 4.1.3.18 (12 Dec 1998) |

| acetometer | <equipment> An instrument for estimating the amount of acetic acid in vinegar or in any liquid containing acetic acid. Origin: L. Acetum = vinegar, F. Acetimetre. Source: Websters Dictionary (01 Mar 1998) |
| acetonaemia | <biochemistry> The condition in which acetone bodies are present in the blood. A condition seen in ketoacidosis (due to alcohol abuse or uncontrolled diabetes). Origin: Gr. Haima = blood (27 Sep 1997) |

| acetone | <chemical> A colourless, flammable liquid which is used as a solvent (it is most familiar as the solvent in nail polish remover). The simplest ketone, it mixes with water, ethyl alcohol, and most oils. It melts at -95.4 deg C. And boils at 56.2 deg C. It is naturally found in very tiny quantities in the body fluids and tissues of healthy people and in somewhat larger amounts in people suffering from diabetes or starvation. (11 Mar 1998) |
| acetone body | <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 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) |
