| farnesene alcohol | <chemical> A colourless liquid extracted from oils of plants such as citronella, neroli, cyclamen, and tuberose. It is an intermediate step in the biological synthesis of cholesterol from mevalonic acid in verterbrates. It has a delicate odour and is used in perfumery. Chemical name: 2,6,10-Dodecatrien-1-ol, 3,7,11-trimethyl- (12 Dec 1998) |

| ketone alcohol | A compound containing a carbonyl or ketone group as well as a hydroxyl group; e.g., dihydroxyacetone. (05 Mar 2000) |
| fatty alcohol | A long chain alcohol, analogous to the fatty acids, of which the fatty alcohol may be viewed as a reduction product; e.g., octadecanol from stearic acid. It is often found esterified in waxes. Synonym: wax alcohol. (05 Mar 2000) |
| foetal alcohol effects | A softer diagnosis than foetal alcohol syndrome (FAS). The diagnosis of possible FAE is considered when: 1. The person has some signs of FAS; 2. The person does not meet all of the necessary criteria for FAS; and 3. There is a history of alcohol exposure before birth. (12 Dec 1998) |
| foetal alcohol syndrome | <syndrome> The most common cause of defective cerebral development in industrialised nations, affecting 1 in 700 live births in the United States. This clinical syndrome results from the direct toxic effects of alcohol on the developing foetus. Growth retardation, mental retardation, small brain and heart valve lesions are common. Infants can be identified by close set eyes, small head, small nasal bridge, reduction in the vermilion border of the upper lip, eye folds and small teeth. (27 Sep 1997) |
| 4-sulfobenzyl alcohol dehydrogenase | <enzyme> Catalyses the formation of 4-sulfobenzaldehyde from 4-sulfobenzyl alcohol; amino acid sequence given in first source Registry number: EC 1.1.1.- Synonym: p-sulfobenzyl alcohol dehydrogenase, tsac protein, tsac gene product (26 Jun 1999) |
| long-chain-alcohol dehydrogenase | <enzyme> Catalyses reversibly the oxidation of a long-chain alcohol in the presence of nad to a long-chain acid anion and NADH Registry number: EC 1.1.1.192 Synonym: fatty alcohol-nad+ oxidoreductase (26 Jun 1999) |
| long-chain-alcohol O-fatty-acyltransferase | <enzyme> Catalyses the final step in biosynthesizing storage liquid waxes from long chain fatty acyl CoA and fatty alcohols; forming predominantly c42 wax esters Registry number: EC 2.3.1.75 Synonym: acyl-coenzyme a-alcohol transacylase, aca transacylase, acyl-CoA-alcohol transacylase, wax-ester synthase (26 Jun 1999) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| 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) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
| acid perfusion test | <gastroenterology, investigation> A test used to diagnosis gastrooesophageal reflux disease. This investigation requires that the patient swallow 3 tiny tubes into the stomach. A mixture of hydrochloric acid (like stomach acid) and saline are alternatively injected into the tubes. The patient then reports any symptoms they may have. Some patients may vomit. (13 Nov 1997) |
| acid phosphatase test for semen | A screening test for semen by determining acid phosphatase content; because seminal fluid contains high concentrations of acid phosphatase, while other body fluids and extraneous foreign materials have very low concentrations, high values of acid phosphatase on vaginal aspirate or lavage, or on wash fluid from stains, render positive identification of semen, even if the male is aspermic.
