| aflatoxin B1 reductase | <enzyme> Reduces the cyclopentenone ring of aflatoxin b1 to aflatoxicol; requires NADPH as cofactor Registry number: EC 1.1.1.- (26 Jun 1999) |
|---|---|
| aflatoxin G2a reductase | <enzyme> Has broad substrate specificity in cell-free extracts from aspergillus parasiticus; versicolorin a hemiacetal is reduced to versicolorin c; 17-hydroxy-16,17-dihydrosterigmatocystin is reduced to a 14,17-hydrated derivative; aflatoxin g2a is converted to a 13,16-hydrated derivative of afg2 Registry number: EC 1.1.1.- (26 Jun 1999) |
| aldehyde reductase | <enzyme> An enzyme that catalyses reversibly the oxidation of an aldose to an alditol. It possesses broad specificity for many aldoses. Chemical name: Alditol:NAD(P)+ 1-oxidoreductase Registry number: EC 1.1.1.21 (12 Dec 1998) |
| aflatoxin | <chemical, microbiology, oncology> A fungal toxin which is a powerful liver carcinogen, found particularly in undeveloped and developing countries. A group of closely related toxic metabolites that are designated mycotoxins. They are produced by aspergillus flavus and a. Parasiticus. Members of the group include aflatoxin b1, aflatoxin b2, aflatoxin g1, aflatoxin g2, aflatoxin m1, and aflatoxin m2. Pharmacological action: carcinogens, mutagens, teratogens. (27 Jun 1999) |
| aflatoxin b1 | <chemical> A potent hepatotoxic and hepatocarcinogenic mycotoxin produced by the aspergillus flavus group of fungi. It is also mutagenic, teratogenic, and causes immunosuppression in animals. It is found as a contaminant in peanuts, cotton seed meal, corn, and other grains. The mycotoxin requires epoxidation to aflatoxin b1 2,3-oxide for activation. Microsomal monooxygenases biotransform the toxin to the less toxic metabolites aflatoxin m1 and q1. Pharmacological action: carcinogens, mutagens, teratogens. Chemical name: Cyclopenta(c)furo(3',2':4,5)furo(2,3-h)(1)benzopyran-1,11-dione, 2,3,6a,9a-tetrahydro-4-methoxy-, (6aR-cis)- (27 Jun 1999) |
| aflatoxin B1 hydroxylase | <enzyme> Hydroxylases may be replaced by mixed function oxidases as appropriate Registry number: EC 1.14.- Synonym: aflatoxin b1 4-hydroxylase (26 Jun 1999) |
| aflatoxin m1 | <chemical> Highly toxic 4-hydroxylated metabolite of aflatoxin b1 found in the milk of cows fed toxic meal. It has mutagenic, carcinogenic, and teratogenic activity. It is formed by the enzymatic hydroxylation of aflatoxin b1 by aflatoxin b1 4-hydroxylase, a cytochrome p-450-dependent enzyme. Pharmacological action: carcinogens, mutagens, teratogens. Chemical name: Cyclopenta(c)furo(3',2':4,5)furo(2,3-h)(1)benzopyran-1,11-dione, 2,3,6a,9a-tetrahydro-9a-hydroxy-4-methoxy-, (6aR-cis)- (27 Jun 1999) |
| acetic aldehyde | <chemical> A colourless, flammable liquid used in the manufacture of acetic acid, perfumes, and flavors. It is also an intermediate in the metabolism of alcohol. It has a general narcotic action and also causes irritation of mucous membranes. Large doses may cause death from respiratory paralysis. Chemical name: Acetaldehyde (12 Dec 1998) |
| active aldehyde | Any aldehyde derivative of thiamin pyrophosphate. (05 Mar 2000) |
| aldehyde | <chemistry> A carbon atom double-bonded to an oxygen, single-bonded to a hydrogen, and single-bonded to another chemical group (such as methane, benzene, another hydrogen, anything). The carbon oxygen double bond part is known as a carbonyl group (C=O). An example is acetaldehyde, which is a carbonyl group single-bonded to a hydrogen and single-bonded to a methane (a methyl group: CH3). (09 Oct 1997) |
| aldehyde base | An obsolete term for an imide. (05 Mar 2000) |
| aldehyde decarbonylase | <enzyme> Catalyses the decarboxylation of aldehydes to form alkanes and co Registry number: EC 4.1.2.- (26 Jun 1999) |
| aldehyde dehydrogenase | <enzyme> An enzyme that oxidises an aldehyde in the presence of NAD+ and water to an acid and NADH. Before 1978, it was classified as EC 1.1.1.70. Chemical name: Aldehyde:NAD+ oxidoreductase Registry number: EC 1.2.1.3 (12 Dec 1998) |
| aldehyde dehydrogenase (acylating) | An oxidoreductase converting an aldehyde and CoA to acyl-CoA with NAD+ as H acceptor. (05 Mar 2000) |
| aldehyde dehydrogenase (NAD+) | An oxidoreductase reversibly converting aldehydes to acids with NADP+ as H acceptor. (05 Mar 2000) |
