| 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 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) |
| 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) |
| vitamin A2 aldehyde | 3-Dehydroretinaldehyde;dehydroretinol with -CHO instead of -CH2OH at the terminal carbon of the side chain. Synonym: retinene-2, vitamin A2 aldehyde. (05 Mar 2000) |
| vitamin A aldehyde | <chemical> A carotenoid constituent of visual pigments. It is the oxidised form of retinol which functions as the active component of the visual cycle. It is bound to the protein opsin forming the complex rhodopsin. When stimulated by visible light, the retinal component of the rhodopsin complex undergoes isomerization at the 11-position of the double bond to the cis-form; this is reversed in "dark" reactions to return to the native trans-configuration. Chemical name: Retinal (03 Jul 1999) |
| glyceric aldehyde | <biochemistry> A type of aldose with the chemical formula C3H6O3. This molecule is used as the reference molecule for handedness (L, lefthanded, or D, right-handed stereochemical configuration) in amino acids, carbohydrates, etc. (09 Oct 1997) |
