| saturated | A condition in which all easily drained voids (pores) between soil particles are temporarily or permanently filled with water, significant saturation during the growing season is considered to be usually one week or more. (09 Oct 1997) |
|---|---|
| saturated colour | A colour containing a minimum amount of whiteness. (05 Mar 2000) |
| saturated fat | A fatty acid with all potential hydrogen binding sites filled (totally hydrogenated fat). These hold the highest risk for the development of atherosclerosis. (27 Sep 1997) |
| saturated fatty acid | A fatty acid, the carbon chain of which contains no ethylenic or other unsaturated linkages between carbon atoms (e.g., stearic acid and palmitic acid); called saturated because it is incapable of absorbing any more hydrogen. (05 Mar 2000) |
| saturated fatty acids | In eukaryotic membranes refers to stearic, palmitic and myristic acids, that are linear aliphatic chains with no double bonds. Prokaryotes have numerous branched chain saturated fatty acids. (18 Nov 1997) |
| saturated hydrocarbon | A hydrocarbon that contains the greatest possible number of hydrogen atoms, so that the molecule contains neither rings nor multiple bonds. (05 Mar 2000) |
| saturated soil | A condition in which all easily drained voids (pores) between soil particles are temporarily or permanently filled with water, significant saturation during the growing season is considered to be usually one week or more. (09 Oct 1997) |
| saturated solution | A solution that contains all of a substance capable of dissolving; a solution of a substance in equilibrium with an excess undissolved substance. (05 Mar 2000) |
| saturated steam | Steam at the temperature that corresponds to its boiling temperature at the same pressure. (05 Dec 1998) |
| saturated steroid 6 alpha-hydroxylase | <enzyme> Acts on 5 alpha-androstane-3 beta,17 beta-diol and 5 alpha-pregnan-3 beta-ol-20-one; does not require cytochrome p-450 Registry number: EC 1.14.99.- Synonym: sat steroid 6alpha-hydroxylase (26 Jun 1999) |
| acetone compound | <biochemistry> Any of the three compounds created by acetyl coenzyme A (acetoacetate, hydroxybutyrate, and acetone) which are water-soluble cellular fuels normally exported by the liver. They can build up in the blood and body tissues because of starvation, untreated diabetes mellitus, or other disorders that interfere with carbohydrate metabolism. The body rids itself of ketones mainly through urine, but it rids itself of acetone through the lungs, which gives the breath a characteristic fruity odour. If ketones build up in the body long enough, they cause serious illness and coma (see ketoacidosis.) (09 Oct 1997) |
| acyclic compound | An organic compound in which the chain does not form a ring. Synonym: aliphatic compound, open chain compound. (05 Mar 2000) |
| addition compound | Strictly, a complex of two or more complete molecules in which each preserves its fundamental structure and no covalent bonds are made or broken (e.g., hydrates of salts, adducts), loosely, association of acids with basic organic compound's (e.g., amines with HCl), more loosely, addition of two molecules without loss of any atom, but forming new covalent bonds (e.g., CH2==CH2 + Br2 → BrCH2-CH2Br). (05 Mar 2000) |
| aliphatic compound | An organic compound in which the chain does not form a ring. Synonym: aliphatic compound, open chain compound. (05 Mar 2000) |
| APC compound | An analgesic tablet drug combination containing aspirin, phenacetin and caffeine. Very widely used in the 1940's through 1960's; original constituents of popular over-the-counter pain remedies. Use currently much diminished due to concerns about potential renal injury due to the phenacetin. (05 Mar 2000) |
