Application

Dihydroxyacetone phosphate (DHAP) is used in fructose metabolism, triose and glycation research. It is used in studies involving the metabolism of three-carbon sugar pools and their roles in physiological and physical processes. DHAP may be used as a substrate to help identify, differentiate and characterize fructose-bisphosphate aldolase(s) (ALDOA) and triosephosphate isomerase(s). DHAP may be used to study cellular glycation stress.

Packaging

5, 10, 25 mg in glass bottle

Biochem/physiol Actions

Dihydroxyacetone phosphate (DHAP) is a metabolic intermediate involved in many pathways, including glycolysis, gluconeogenesis, glycerol metabolism, phosphatidic acid synthesis, fat metabolism, and the Calvin cycle.

Caution

Unlike the dimethyl ketal, does not require hydrolysis prior to use as a substrate.

Preparation Note
