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.

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.


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

Preparation Note

Enzymatically prepared.

In the diagnosis of Alzheimer's disease (AD) total tau (T-tau), tau phosphorylated at threonine 181 (P-tau181), and the 42 amino acid isoform of alpha β-amyloid (Aβ) are well established surrogate CSF markers. However, there is a constant need for new...

Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry has been widely used for biomolecular analysis. However, with conventional MALDI, it is difficult to analyse low-molecular-weight compounds because of the interference of matrix ion signals. Here, we report a matrix-free on-chip pulse-heating desorption/ionization...

Sugar-derived reactive carbonyls (RCs), including methylglyoxal (MG), are aggressive by-products of oxidative stress known to impair the functions of multiple proteins. These advanced glycation end-products accumulate in patients with diabetes mellitus and cause major complications, including arteriosclerosis and cardiac insufficiency....

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.
