|---|---|
| alpha-(N-acetylaminomethylene)succinic acid hydrolase | <enzyme> Involved in degradation of vitamin b6; forms acetic acid plus ammonia plus carbon dioxide plus succinic monoaldehyde Registry number: EC 3.5.1.- Synonym: compound a hydrolase (26 Jun 1999) |
| alpha-N-acetyl-D-glucosaminidase | <enzyme> Believed to be deficient in sanfilippo syndrome type b Registry number: EC 3.2.1.50 Synonym: alpha-n-acetylglucosaminidase (26 Jun 1999) |
| alpha-N-acetylgalactosaminidase | <enzyme> An enzyme that hydrolyzes 2-acetamido-2-deoxy-alpha-d-galactosides to the alcohol and free 2-acetamido-2-deoxy-d-galactose. A deficiency of this enzyme will result in Schindler disease. (05 Mar 2000) |
| alpha-N-acetylglucosaminidase | <enzyme> An enzyme that hydrolyzes glycosides of N-acetylglucosamine producing the alcohol and N-acetylglucosamine. A deficiency of this enzyme results in mucopolysaccharidosis III B. (05 Mar 2000) |

| alpha-naphthylthiourea | 1-(1-Naphthyl)-2-thiourea;a derivative of thiourea; a highly toxic antithyroid agent, especially to small mammals, causing pulmonary oedema, fatty degeneration of the liver, and low body temperature; used as a rat poison. Acronym: ANTU (05 Mar 2000) |
| alpha-neoagarooligosaccharide hydrolase | <enzyme> Hydrolyzes the alpha-1,3 linkage of neoagarooligosaccharides; from marine bacterium, vibrio sp.; mw 42 kD; amino acid sequence has been determined Registry number: EC 3.2.1.- Synonym: alpha-naos hydrolase (26 Jun 1999) |
| alpha-oxidation | A form of oxidation of fatty acids in which carbons are removed one at a time in the form of CO2; the alpha-carbon is first hydroxylated and then converted into a carbonyl; a deficiency of this pathway is associated with Refsum's disease. (05 Mar 2000) |
| alpha particle | <physics> A radioactive particle made up of two protons and two neutrons, these particles are created by the decay of a radioactive material or by nuclear bombardment, and they are the same as the nucleus of a helium-4 atom. (09 Oct 1997) |
| alpha particles | Positively charged particles composed of two protons and two neutrons, i.e., helium nuclei, emitted during disintegration of very heavy isotopes; a beam of alpha particles or an alpha ray has very strong ionizing power, but weak penetrability. (12 Dec 1998) |
