| ES46.5K esterase | <enzyme> Hepatic, microsomal enzyme that catalyses hydrolysis of phthalate esters Registry number: EC 3.1.1.- (26 Jun 1999) |
| esterase | <enzyme> An enzyme that catalyses the hydrolysis of organic esters to release an alcohol or thiol and acid. The term could be applied to enzymes that hydrolyse carboxylate, phosphate and sulphate esters, but is more often restricted to the first class of substrate. (18 Nov 1997) |
| juvenile hormone esterase | <enzyme> Amino acid sequence has been determined Registry number: EC 3.1.1.- Synonym: jh esterase, insect jhe (26 Jun 1999) |
| feruloyl-4-coumaroyl esterase | <enzyme> From penicillium pinophilum; releases ferulic acid and para-coumaric acid from esterified wheat straw xylan; can also release acetic acid from p-nitrophenyl acetate and from an acetylated xylan; acts synergistically with celluclast Registry number: EC 3.1.1.- Synonym: fc esterase (26 Jun 1999) |
| feruloyl esterase | <enzyme> Splits ester bond of methyl 5-o-feruloylarabinofuranoside to release ferulic acid; see also record for feruloyl-4-coumaroyl esterase Registry number: EC 3.1.1.- Synonym: ferulic acid esterase (26 Jun 1999) |
| 4-nitrobenzyl esterase | <enzyme> Catalyses the hydrolysis of several beta-lactam p-nitrobenzyl (pnb) esters to the corresponding free acid and pnb alcohol; genbank u06089 Registry number: EC 3.1.1.- Synonym: p-nitrobenzyl esterase, pnb carboxy-esterase, pnbce, pnba protein, pnba gene product (26 Jun 1999) |
| 60kDa glycoprotein esterase | <enzyme> Mw appr. 60kda; from liver microsomes; amino acid sequence given in jbc 1987;262(31):15316 Registry number: EC 3.1.- Synonym: carboxyesterase gp60a, carboxyesterase gp60b (26 Jun 1999) |
| leukocyte esterase | <enzyme> The presence of leukocyte esterase is indirect evidence for the presence of white blood cells in the urine. The standard urinalysis dip test allows for the quick determination of leukocyte esterase presence via a colour reaction on a urine test strip. A positive test indicates a urinary tract infection. (27 Sep 1997) |
| 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.

| 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) |
