Dhap phosphate
WebParaquat also decreased purine levels (ATP, ADP, and AMP) and metabolites associated the glycolytic pathway [3-phospho glycerate, dihydroxyacetone phosphate (DHAP or glycerone phosphate), lactate, and alanine]. A decrease in extracellular glucose, lactate, and alanine was also observed. WebIncreased concentrations of DHAP and glyceraldehyde-3-phosphate in the liver drive the gluconeogenic pathway toward glucose-6-phosphate, glucose-1-phosphate and glycogen formation. It appears that fructose is a better substrate for glycogen synthesis than glucose and that glycogen replenishment takes precedence over triglyceride formation.

Its major biochemical role is in the glycolysis metabolic pathway. DHAP may be referred to as glycerone phosphate in older texts.
WebWe show that mTORC1 senses a metabolite downstream of the aldolase and upstream of the GAPDH-catalysed steps of glycolysis and pinpoint dihydroxyacetone phosphate … WebGlyceraldehyde 3-phosphate, also known as triose phosphate or 3-phosphoglyceraldehyde and abbreviated as G3P, GA3P, GADP, GAP, TP, GALP or …
WebDHAP can be diverted from its precursor role in ether lipid synthesis by conversion to sn-glycerol-3-phosphate by NADH:glycerol-3-phosphate dehydrogenase. Another bypass that prevents the formation of alkyl-DHAP occurs if the ketone function of acyl-DHAP is first reduced by an NADPH-dependent oxidoreductase, since the product, 1-acyl-2-lyso sn ...
WebThe triosephosphate isomerase 1 enzyme carries out a specific reaction during glycolysis: the conversion of a molecule called dihydroxyacetone phosphate (DHAP) to glyceraldehyde 3-phosphate.
