Fructokinase (/fruc•to•ki•nase/ [-ki´nas]), also known as D-fructokinase or D-fructose (D-mannose) kinase,[1] is an enzyme (EC 2.7.1.4) of the liver, intestine, and kidney cortex. Fructokinase is in a family of enzymes called transferases, meaning that this enzyme transfers functional groups; it is also considered a phosphotransferase (or, frequently, a kinase) since it specifically transfers a phosphate group.[1] Fructokinase specifically catalyzes the transfer of a phosphate group from adenosine triphosphate (ATP, the substrate) to fructose as the initial step in its utilization.[1] The main role of fructokinase is in carbohydrate metabolism, more specifically, sucrose and fructose metabolism. The reaction equation is as follows:
- ATP + D-fructose → ADP + D-fructose 1-phosphate.
