A monosaccharide potentially containing the characteristic group of the aldehydes, —CHO; a polyhydroxyaldehyde.
- a. mutarotase SYN: a. 1-epimerase.
- a. reductase polyol dehydrogenase (NADP+); an oxidoreductase that reversibly converts aldoses to alditols ( e.g., glucose to sorbitol) with NADPH as hydrogen donor. An important step in the metabolism of sorbitol and in the formation of diabetic cataracts. SEE ALSO: d-sorbitol-6-phosphate dehydrogenase.

al·dose 'al-.dōs, -.dōz n a sugar containing one aldehyde group per molecule

* * *

al·dose (alґdōs) one of two subgroups of monosaccharides, being those having a terminal carbonyl (aldehyde) group; it is further subdivided on the basis of the number of carbon atoms in the sugar; see aldotetrose, aldopentose, aldohexose, etc. Examples are glucose, galactose, and mannose.
