Dihydroxyacetone Phosphate (DHAP)

An intermediate in glycolysis, gluconeogenesis, glycerophospholipid, glycerol metabolism, phosphatidic acid synthesis, fat metabolism, and the Calvin Cycle.

DHAP is also employed in the glycerophosphate shuttle, which functions as an electron-transporting mechanism in insect muscle (Figure 15.11a).

Enzymes that act on DHAP include the following:

Glyceraldehyde-3-phosphate dehydrogenase

Triosephosphate Isomerase

Glycerol-3-Phosphate Dehydrogenase

Aldolase

Aldolase B
