WebJul 20, 2024 · Fructose 1,6-bisphosphate aldolase (EC 4.1.2.13) is an enzyme that participates in both the glycolytic (sugar catabolism) and gluconeogenesis (sugar synthesis) biochemical pathways. The reaction catalyzed by fructose 1,6-bisphosphate aldolase links two 3-carbon sugars, glyceraldehyde-3-phosphate (GAP, the electrophile in the reaction) … WebFructose-1,6-biphosphate is then cleaved by the aldolase into two C3-units: Dihydroxyacetone phosphate (DHAP) and Glyceraldehyde 3-phosphate (GA-3-P). GA-3-P is converted into DHAP, so that downstream only one metabolite needs to be processed.
