| dihydroxyacetone | <chemical> 1,3-dihydroxy-2-propanone. A ketotriose compound. Its addition to blood preservation solutions results in better maintenance of 2,3-diphosphoglycerate levels during storage. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones it acts as a sunscreening agent. Chemical name: 2-Propanone, 1,3-dihydroxy- (12 Dec 1998) |
| dihydroxyacetone phosphate | This is an intermediate molecule involved in the fourth step of glycolysis. Dihydroxyacetonephosphate is created from fructose 1,6-bisphosphate. In step 5, it is converted into its positional isomer, glyceraldehyde3-phosphate, with the aid of triose-phosphate isomerase. (09 Oct 1997) |
