| neutral lipid storage disease | <syndrome> Congenital ichthyosis, leukocyte vacuoles, and variable involvement of other organ systems. Synonym: neutral lipid storage disease. (05 Mar 2000) |
|---|---|
| substrate-level phosphorylation | Synthesis of high-energy phosphate bonds through reaction of inorganic phosphate with an activated (usually) organic substrate. (09 Oct 1997) |
| no-observed-adverse-effect level | The highest dosage administered that does not produce toxic effects. The noael will depend on how closely dosages are spaced (lowest-observed-adverse-effect level and no-observed-effect level) and the number of animals examined. The ultimate objective is usually to determine not the "safe" dosage in laboratory animals but the "safe" dosage for humans. Therefore, the extrapolation most often required of toxicologists is from high-dosage studies in laboratory animals to low doses in humans.

| disease, lipid storage | A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (Examples include Gaucher, Fabry and Niemann-Pick diseases and metachromatic leukodystrophy). (12 Dec 1998) |
| inositol lipid | A membrane-anchored phospholipid that transduces hormonal signals by stimulating the release of any of several chemical messengers. (09 Oct 1997) |
| isotropic lipid | A lipid occurring in the form of singly refractive droplets. (05 Mar 2000) |
| organic level | The amount of organic matter prescribed to be left after logging. (05 Dec 1998) |
| trophic level | <biology> Stage in a food chain or web leading from primary producers (lowest trophic level) through herbivores to primary and secondary carnivores (consumers- highest level). (09 Oct 1997) |
| lactate level | A test that measures the amount of lactic acid in the blood. Lactic acid is an intermediate product of carbohydrate metabolism and is derived mainly from muscle cells and red blood cells. Exercise will normally raise lactic acid levels. Conditions of oxygen deprivation (for example shock, heart failure, lung disease) will trigger anaerobic metabolism within muscle tissue resulting in lactic acid build up in the tissues. Normal lactic acid levels are 4.5 to 19.8 mg/dl. (27 Sep 1997) |
| lactic acid level | <investigation> A test that measures the amount of lactic acid in the blood. (25 Jun 1999) |
| free calcium level | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |
| level of aspiration | <psychology> The degree or quality of performance (exhibited in a testing situation) which an individual desires to attain or feels he can achieve. (05 Mar 2000) |
| lipid | <chemical> Any of a heterogeneous group of flats and fatlike substances characterised by being water insoluble and being extractable by nonpolar (or fat) solvents such as alcohol, ether, chloroform, benzene, etc. All contain as a major constituent aliphatic hydrocarbons. The lipids, which are easily stored in the body, serve as a source of fuel, are an important constituent of cell structure and serve other biological functions. Lipids may be considered to include fatty acids, neutral fats, waxes and steroids. Compound lipids comprise the glycolipids, lipoproteins and phospholipids. (18 Nov 1997) |
| lipid A | The lipid associated with polysaccharide in the lipopolysaccharide of gram-negative bacterial cell walls. (18 Nov 1997) |
| lipid A 4'-phosphatase | <enzyme> Involved in lipid a biosynthesis in rhizobium leguminosarum Registry number: EC 3.1.3.- Synonym: 2-keto-3-deoxyoctulosonate-activated 4'-phosphatase, kdo-activated lipid a 4'-phosphatase (26 Jun 1999) |
