Can fructose be used in glycolysis

WebIn the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate. An enzyme that catalyzes the conversion of a molecule into one of its isomers is an isomerase. (This change from phosphoglucose to phosphofructose allows the eventual split of the sugar into two three-carbon molecules). Step 3. WebPFKs are the following rate-limiting enzyme in glycolysis involved in the catalyzation of the third reaction of glycolysis, i.e., the conversion of fructose-6-phosphate (F6P) to fructose-1,6-bisphosphate (F1,6BP) via transferring a phosphate group from ATP. ... Thus, PFK can be used as a metabolic target in cancer therapy.
