dihydroxyacetonen.

Etymology: < di- comb. form + hydroxy- comb. form + acetone n.Previous versions of the OED give the stress as: ˌdihydroxyˈacetone.

Chemistry.

A colourless crystalline compound, CH₂OH·CO·CH₂OH, isomeric with glyceraldehyde and having strong reducing properties.

ΚΠ

1895 Jrnl. Chem. Soc. 68 i. 496 Attempts to prepare dihydroxyacetone by the action of nitrous acid on diamidoacetone hydrochloride were not very successful.

1951 I. L. Finar Org. Chem. xviii. 358 Dihydroxyacetone..is not optically active, and hence, by the definition given above, is not a sugar. If..the proviso that a sugar is always optically active is rejected, then dihydroxyacetone will be a ketotriose.

1967 I. L. Finar Org. Chem. (ed. 5) I. xi. 287 Bromine water, sodium hypobromite and Fenton's reagent..oxidise glycerol to a mixture of glyceraldehyde (predominantly) and dihydroxyacetone; this mixture is known as glycerose.

1969 J. H. Ottaway & F. M. Irvine tr. H. Netter Theoret. Biochem. xiii. 715 In the mitochondria a very active oxidation of glycerol phosphate takes place. The dihydroxyacetone phosphate which is formed diffuses into the cytoplasm,..and so acts as a transporter of hydrogen to the respiratory chain.
