Detailed explanation-1: -The balance between DHAP and G3P is extremely important in regulating overall cell metabolism. DHAP is a precursor to triglycerides, and is used in their synthesis, while G3P is an intermediate in glycolysis, an ATP-producing process.
Detailed explanation-2: -Human liver glycerol-3-phosphate dehydrogenase (hlGPDH) catalyzes the reduction of dihydroxyacetone phosphate (DHAP) to form glycerol 3-phosphate, using the binding energy associated with the nonreacting phosphodianion of the substrate to properly orient the enzyme-substrate complex within the active site.
Detailed explanation-3: -The glyceraldehyde 3-phopshate lies directly on the glycolytic pathway and so goes on to stage three. On the other hand, dihydroxyacetone phosphate does not and so needs to be converted into a glyceraldehyde 3-phopshate molecule before it can be used by the glycolytic pathway.
Detailed explanation-4: -Glycerol-3-phosphate dehydrogenase serves as a major link between carbohydrate metabolism and lipid metabolism. It is also a major contributor of electrons to the electron transport chain in the mitochondria.
