DHAP (or Dihydroxyacetonephosphate) is a biochemical compound involved in many reactions, from the Calvin Cycle in plants to the ether-lipid biosynthesis process in Leishmania mexicana.
In the Calvin Cycle, it is one of the products of the sixfold reduction of 1,3-Bisphosphoglycerate by NADPH. It is also used in the synthesis of Sedoheptulose 1,7-bisphosphate and Fructose 1,6-bisphosphate which are both used to reform Ribulose 5-Phosphate, the 'key' carbohydrate of the Calvin cycle.
