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. Prod. by microorganisms, e.g. Corynebacterium diphtheriae (CCD) Dihydroxyacetone or DHA, also known as glycerone, is a triose with formula C3H6O3. DHA is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin. (Wikipedia)
