| ALDH-3 | aldehyde dehydrogenase |
| 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) |
| Gomori's aldehyde fuchsin stain | <technique> A stain used to demonstrate beta cells of the pancreas, storage form of thyrotrophic hormone in beta cells of the anterior pituitary, hypophyseal neurosecretory substance, mast cells, granules, elastic fibres, sulfated mucins, and gastric chief cells. (05 Mar 2000) |
| methyl aldehyde | <chemical> Commonly used fixative and antibacterial agent. As a fixative it is cheap and tends to cause less denaturation of proteins than does glutaraldehyde, particularly if used in a well buffered solution (buffered formalin, formal saline). Old formaldehyde solutions usually contain cross linking contaminants and it is therefore often preferable to used a formaldehyde generating agent such as paraformaldehyde. Formalin fumes, particularly in conjunction with hydrochloric acid vapour, are potently carcinogenic. (20 Jun 2000) |
| cinnamic aldehyde | 3-phenylpropenal;chief constituent of cinnamon oil. Synonym: cinnamic aldehyde. (05 Mar 2000) |
| molybdenum-iron protein aldehyde oxidoreductase | <enzyme> Related to xanthine oxidase; isolated from desulfovibrio gigas Registry number: EC 1.2.7.- Synonym: mop protein (26 Jun 1999) |
| salicylic aldehyde | salicyl aldehyde |
| pyruvic aldehyde | CH3-CO-CHO; Pyruvaldehyde;the aldehyde of pyruvic acid; an intermediate of carbohydrate metabolism in certain organisms. Synonym: pyruvic aldehyde. Methylglyoxal bis(guanylhydrazone), 1,1'-[(methylethanediylidene)dinitrilo]diguanidine;an antineoplastic agent. (05 Mar 2000) |
| sugar aldehyde | A sugar that contains an internal acetal. (05 Mar 2000) |
| ketone-aldehyde mutase | <enzyme> An enzyme that catalyses the interconversion of methylglyoxal and lactate, with glutathione serving as a coenzyme. Chemical name: S-Lactoyl-glutathione methylglyoxal-lyase (isomerizing) Registry number: EC 4.4.1.5 (12 Dec 1998) |
| formic aldehyde | <chemical> Commonly used fixative and antibacterial agent. As a fixative it is cheap and tends to cause less denaturation of proteins than does glutaraldehyde, particularly if used in a well buffered solution (buffered formalin, formal saline). Old formaldehyde solutions usually contain cross linking contaminants and it is therefore often preferable to used a formaldehyde generating agent such as paraformaldehyde.
