fructokinase

 [fruk″to-ki´nās]
an enzyme that catalyzes the transfer of a high-energy phosphate group to d-fructose.

fruc·to·ki·nase

(fruk'tō-kī'nās),
A liver enzyme that catalyzes the reaction of ATP and d-fructose to form fructose 6-phosphate and ADP; deficient in individuals with essential fructosuria (hepatic fructokinase deficiency).

fructokinase

/fruc·to·ki·nase/ (-ki´nās) an enzyme of the liver, intestine, and kidney cortex that catalyzes the transfer of a phosphate group from ATP to fructose as the initial step in its utilization. Deficiency causes essential fructosuria.

fructokinase

[fruk′tōkī′nās]
an enzyme that catalyzes the transfer of a high-energy phosphate group from adenosine triphosphate to d-fructose.

fruc·to·ki·nase

(fruk'tō-kī'nās)
A liver enzyme that catalyzes the reaction of ATP and d-fructose to form fructose 6-phosphate and ADP; deficient in patients with essential fructosuria (hepatic fructokinase deficiency).

fructokinase

an enzyme that catalyzes the transfer of a high-energy phosphate group to d-fructose, to form fructose-1-phosphate.

The team got similar results when they gave the glucose water to mice engineered to lack fructokinase, an enzyme that trips the chain reaction by which fructose is metabolized.
This strong anti-inflammatory activity of atorvastatin could be attributed to two factors: the well-known inhibition of NFkB activity by atorvastatin and the reduced liver metabolism of fructose, resulting from atorvastatin-mediated decreased expression of fructokinase, thus alleviating hepatic metabolic stress and the production of pro-inflammatory products.

When fructose is ingested, it is acted upon by the enzyme fructokinase to produce fructose-1-phosphate, consuming in the process one molecule of ATP and generating ADP and inorganic phosphate ([P.
Ketohexokinase or hepatic fructokinase catalyzes the first step in the metabolism of dietary fructose to produce energy, converting fructose into fructose-1-phosphate; malfunction of this enzyme causes diabetes mellitus (Hayward et al.
