| labarraque's solution | <medicine> An aqueous solution of hypochlorite of sodium, extensively used as a disinfectant. Origin: From Labarraque, a Parisian apothecary. Source: Websters Dictionary (01 Mar 1998) |
| lactated Ringer's solution | A solution containing NaCl, sodium lactate, CaCl2(dihydrate), and KCl in distilled water; used for the same purposes as Ringer's solution. Synonym: Hartmann's solution. (05 Mar 2000) |
| Fonio's solution | A diluent with magnesium sulfate, used for stained smears of blood platelets. (05 Mar 2000) |
| Lange's solution | A colloidal gold solution used to demonstrate protein abnormalities in spinal fluid. See: Lange's test. (05 Mar 2000) |
| fowler's solution | An quenous solution of arsenite of potassium, of such strength that one hundred parts represent one part of arsenious acid, or white arsenic; named from Fowler, an English physician who first brought it into use. Source: Websters Dictionary (01 Mar 1998) |
| Locke-Ringer solution | A solution containing NaCl, CaCl2, KCl, MgCl2, NaHCO3, d-glucose, and water; used in the laboratory for physiological and pharmacological experiments. (05 Mar 2000) |
| Lugol's iodine solution | An iodine-potassium iodide solution used as an oxidizing agent, for removal of mercurial fixation artifacts, and also in histochemistry and to stain amoebas. (05 Mar 2000) |
| acetate | <biochemistry> A salt or ester of acetic acid, specifically, a synthetic textile fibre made from partially hydrolysed cellulose acetate, or a plastic-like film made from cellulose triacetate. The terminal hydrogen atom in the molecule is replaced by a metal, for instance copper acetate, or where substitution is by a radical, for instance ethyl acetate. (04 Jul 1999) |
| acetate-CoA ligase | <enzyme> An enzyme that catalyses the formation of CoA derivatives from ATP, acetate, and CoA to form AMP, pyrophosphate, and acetyl CoA. It acts also on propionates and acrylates. Chemical name: Acetate:CoA ligase (AMP-forming) Registry number: EC 6.2.1.1 (12 Dec 1998) |
| acetate kinase | <enzyme> An enzyme that catalyses reversibly the phosphorylation of acetate in the presence of a divalent cation and ATP with the formation of acetylphosphate and ADP. It is important in the glycolysis process. Chemical name: ATP:acetate phosphotransferase Registry number: EC 2.7.2.1 (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| acetate-succinate CoA-transferase | <enzyme> Tritichomonas and trichomonas enzyme converts acetyl-CoA and succinate to acetate and succinyl-CoA Registry number: EC 2.8.3.- Synonym: acetate-succinate coenzyme a-transferase (26 Jun 1999) |
| acetate thiokinase | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
| active acetate | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
