| potassium magnesium aspartate | <chemical> An intra-extracellular electrolyte exchange agent with a variety of effects. Beneficial in cardiac insufficiency, potentiates the effect of cardiac glycosides by reducing their toxicity, has hypocholesteraemic effects and potentiates the effects of calcium in disturbed calcium metabolism. Synonym: panangin; tromcardin. Chemical name: DL-Aspartic acid, monopotassium salt, mixt. With potassium hydrogen (T-4)-bis(DL-aspartato(2-)-N,O1)magnesate(2-) (12 Dec 1998) |

| deficiency, magnesium | Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesaemia) is often associated with low calcium (hypocalcaemia) and potassium (hypokalaemia) levels. Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the National Academy of Sciences, the Recommended Dietary Allowances of magnesium are 420milligrams per day for men and 320 milligrams per day for women. The upperlimit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| effervescent magnesium citrate | Magnesium carbonate, citric acid, sodium bicarbonate, and sugar, moistened with alcohol, passed through a sieve, and dried to a coarse granular powder; used as a laxative. (05 Mar 2000) |
| effervescent magnesium sulfate | Effervescent Epsom salt; magnesium sulfate, sodium bicarbonate, tartaric acid, and citric acid, moistened, passed through a sieve, and dried to a coarse granular powder; a purgative. (05 Mar 2000) |
| tribasic magnesium phosphate | Mg3(PO4)2-5H2O;tertiary magnesium phosphate, it is used as an antacid but it does not produce systemic alkalization; 1 g is equivalent in neutralizing power to about 0.46 g of sodium bicarbonate. (05 Mar 2000) |
| administration, oral | The giving of drugs, chemicals, or other substances by mouth. (12 Dec 1998) |
| amino- | <prefix> Prefix denoting a compound containing the radical, -NH2. Origin: an(monia) + in(e) + -o- (05 Mar 2000) |
| amino acids | Organic compounds that generally contain an amino (-nh2) and a carboxyl (-cooh) group. Twenty alpha-amino acids are the subunits which are polymerised to form proteins. (12 Dec 1998) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
| amino acyl-tRNA ligases | <enzyme> Any of the group of ligases that catalyses the ATP-driven formation of a bond between an amino acid and a trna, activating the amino acids as a step in protein synthesis. Individual enzymes are highly specific for one amino acid and for any trna corresponding to that amino acid. Registry number: EC 6.1.1. (12 Dec 1998) |
| amino alcohols | Compounds possessing both a hydroxyl (-oh) and an amino group (-nh2). (12 Dec 1998) |
| amino group | <biochemistry> An -NH2 group. Organic compounds which have this group are called amines. (09 Oct 1997) |
| amino sugar | <biochemistry> Monosaccharide in which an OH group is replaced with an amino group, often acetylated. Common examples are D galactosamine, D glucosamine, neuraminic acid, muramic acid. Amino sugars are important constituents of bacterial cell walls, some antibiotics, blood group substances, milk oligosaccharides and chitin. (18 Nov 1997) |
