WebFructose Metabolism. Fructose metabolism is best understood by considering three enzymes: fructokinase, fructose-bisphosphate aldolase B, and adenosine triphosphate (ATP)-dependent dihydroxyacetone kinase (or triokinase). All three of these are only found in the liver and kidneys of rats and humans. In the liver, fructose is rapidly converted ... WebGlucose (hexose sugar) is activated for subsequent reactions by its phosphorylation to yield glucose 6-phosphate, with ATP as the phosphoryl donor. This reaction, which is irreversible under intracellular conditions, is catalyzed by enzyme hexokinase, which requires Mg 2+ for its activity.
