| STANDOUT | soft thresholding and depth cueing of unspecified techniques |
| soft water | Water lacking those ions, such as Magnesium and Calcium, that form insoluble salts with fatty acids, so that ordinary soap will lather easily in it. (05 Mar 2000) |

| nasion soft tissue | The outer point of intersection between the nasion-sella line and the soft tissue profile. (05 Mar 2000) |
| neoplasms, connective and soft tissue | Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue. (12 Dec 1998) |
| tensor muscle of soft palate | <anatomy> Tensor muscle of soft palate, musculus tensor palati; musculus palatosalpingeus; musculus sphenosalpingostaphylinus; dilator tubae; origin, scaphoid fossa of sphenoid, cartilaginous and membranous part of auditory (eustachian) tube and spine of sphenoid; insertion, posterior border of hard palate and aponeurosis of soft palate; action, tenses the soft palate; contributes to opening of auditory tube; nerve supply, branches of trigeminal nerve through the otic ganglion. Synonym: musculus tensor veli palatini, dilator tubae, musculus palatosalpingeus, musculus sphenosalpingostaphylinus, musculus tensor palati, palatosalpingeus, tensor muscle of soft palate. (05 Mar 2000) |
| elevator muscle of soft palate | <anatomy, muscle> Origin, apex of petrous portion of temporal bone and lower part of cartilaginous auditory (eustachian) tube; insertion, aponeurosis of soft palate; action, raises soft palate; through the expansion of its fleshy belly during contraction, it helps to "push" open the auditory tube; nerve supply, pharyngeal plexus (cranial root of accessory nerve). Synonym: musculus levator veli palatini, elevator muscle of soft palate, levator palati muscle, musculus levator palati, musculus petrostaphylinus. (05 Mar 2000) |
| yellow soft paraffin | <pharmacology> A semisolid unctuous substance, neutral, and without taste or odour, derived from petroleum by distilling off the lighter portions and purifying the residue. It is a yellowish, fatlike mass, transparent in thin layers, and somewhat fluorescent. It is used as a bland protective dressing, and as a substitute for fatty materials in ointments. Petrolatum is the official name for the purified product. Cosmoline and vaseline are commercial names for substances essentially the same, but differing slightly in appearance and consistency or fusibility. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| aluminum acetate | Used as a disinfectant by embalmers; proposed as desiccant and deodorant powder for eczema and chronic skin ulcers. (05 Mar 2000) |
| anagestone acetate | 17-Hydroxy-6alpha-methylpregn-4-en-20-one acetate;a progestational agent. (05 Mar 2000) |
