| aldehyde dehydrogenase (NAD(P)+) | An oxidoreductase reversibly converting aldehydes to acids with NAD+ or NADP+ as H acceptor. (05 Mar 2000) |
|---|---|
| aldehyde DPN transhydrogenase | aldehyde dehydrogenase (NAD+) |
| aldehyde ferredoxin oxidoreductase | <enzyme> Contains molybdopterin as the organic component of tungsten cofactor Registry number: EC 1.2.7.- (26 Jun 1999) |
| aldehyde fuchsin | A stain developed by Gomori, utilizing basic fuchsin paraldehyde and hydrochloric acid; it produces violet staining of elastic fibres, mast cell granules, gastric chief cells, beta cells of the pancreatic islets, and certain hypophyseal beta granules; other pituitary granules and cells stain in other colours. See: Gomori's aldehyde fuchsin stain. (05 Mar 2000) |
| aldehyde-ketone transferases | <enzyme> Enzymes that catalyze the transfer of aldehyde or ketone residues. Registry number: EC 2.2 (12 Dec 1998) |
| aldehyde-lyases | <enzyme> Enzymes that catalyze cleavage of a carbon-carbon bond in a molecule containing a hydroxyl group and a carbonyl group to form two smaller molecules, each being an aldehyde or a ketone. The reaction is the reverse of an aldol condensation. These enzymes are also known as aldolases. Registry number: EC 4.1.2. (12 Dec 1998) |
| aldehyde oxidase | <enzyme> Broad substrate specificity Registry number: EC 1.2.3.1 Synonym: n1-methylnicotinamide oxidase I, n-nitrosoreductase (26 Jun 1999) |
| aldehyde oxidoreductases | <enzyme> Registry number: EC 1.2. (12 Dec 1998) |
| aldehyde reaction | The reaction of the indole derivatives with aromatic aldehydes; e.g., tryptophan and p-dimethylaminobenzaldehyde in H2SO4 give a red-violet colour useful in assaying proteins for tryptophan content. Synonym: Ehrlich reaction. (05 Mar 2000) |
| aldehyde TPN transhydrogenase | <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 transhydrogenase | <enzyme> An enzyme that catalyses reversibly the final step of alcoholic fermentation by reducing an aldehyde to an alcohol. In the case of ethanol, acetaldehyde is reduced to ethanol in the presence of NADH and hydrogen. The enzyme is a zinc protein which acts on primary and secondary alcohols or hemiacetals. Chemical name: Alcohol:NAD+ oxidoreductase Registry number: EC 1.1.1.1 (12 Dec 1998) |
| angular aldehyde | The aldehyde group attached to carbon 13 (between rings C and D) of the steroid nucleus in aldosterone. (05 Mar 2000) |
| benzoic aldehyde | C6H5CHO;an aldehyde produced artificially or obtained from oil of bitter almond, containing not less than 80% of benzaldehyde; a flavoring agent used in orally administered medicines. Synonym: benzoic aldehyde. (05 Mar 2000) |
| benzylviologen-linked aldehyde oxidoreductase | <enzyme> A coenzyme a-independent tungsten-containing aldehyde oxidoreductase; from desulfovibrio gigas; n-terminal amino acid sequence given in first source Registry number: EC 1.2.7.- Synonym: bv-aldh (26 Jun 1999) |
| betaine-aldehyde dehydrogenase | An oxidizing enzyme that catalyses the oxidation of betaine aldehyde with NAD+ and water to betaine and NADH; part of the choline oxidase system and of choline metabolism. (05 Mar 2000) |
