| aminopeptidases | <enzyme> Registry number: EC 3.4.11. (12 Dec 1998) |
| aminophenazone | <chemical> A drug with analgesic, anti-inflammatory, and antipyretic properties but, owing to the risk of agranulocytosis, whose use is discouraged. Pharmacological action: non-steroidal anti-inflammatory agents. Chemical name: 3H-Pyrazol-3-one, 4-(dimethylamino)-1,2-dihydro-1,5-dimethyl-2-phenyl- (12 Dec 1998) |
| aminophenols | Phenols substituted in any position by an amino group. (12 Dec 1998) |
| aminopherases | Enzymes transferring amino groups between an amino acid to (usually) a 2-keto acid; e.g., l-alanine and 2-ketoglutarate. Often, the amino acid is an alpha-amino acid. Synonym: aminopherases, transaminases. (05 Mar 2000) |

| aminopromazine | 10-[2,3-Bis(dimethylamino)propyl]phenothiazine;an intestinal antispasmodic. (05 Mar 2000) |
| aminopropionic acid | <amino acid> Alanine is a nonessential amino acid that can be manufactured by the body from other sources as needed. Alanine is one of the simplest of the amino acids and is involved in the energy-producing breakdown of glucose. In conditions of sudden anaerobic energy need, when muscle proteins are broken down for energy, alanine acts as a carrier molecule to take the nitrogen-containing amino group to the liver to be changed to the less toxic urea, thus preventing buildup of toxic products in the muscle cells when extra energy is needed. Because the body easily constructs alanine from other sources, no deficiency state is known. Alanine is found in a wide variety of foods, but is particularly concentrated in meats. (22 May 1997) |
| aminopropionitrile | <chemical> 3-aminopropanenitrile. Reagent used as an intermediate in the manufacture of beta-alanine and pantothenic acid. Chemical name: Propanenitrile, 3-amino- (12 Dec 1998) |

| aminopyrine | <chemical> A drug with analgesic, anti-inflammatory, and antipyretic properties but, owing to the risk of agranulocytosis, whose use is discouraged. Pharmacological action: non-steroidal anti-inflammatory agents. Chemical name: 3H-Pyrazol-3-one, 4-(dimethylamino)-1,2-dihydro-1,5-dimethyl-2-phenyl- (12 Dec 1998) |
