Hexokinase III, also known as hexokinase C, is an enzyme which in humans is encoded by the Hk3 gene on chromosome 5. [ 5 ] [ 6 ] Hexokinases phosphorylate glucose to produce glucose-6-phosphate , the first step in most glucose metabolism pathways.
Glucokinase can only phosphorylate glucose if the concentration of this substrate is high enough; it does not follow Henri–Michaelis–Menten kinetics, and has no K m; It is half-saturated at glucose concentrations 100 times higher than those of hexokinases I, II, and III. Hexokinase IV is monomeric, about 50kDa, displays positive ...
Hexokinase is inhibited by high levels of G6P in the cell. Thus the rate of entry of glucose into cells partially depends on how fast G6P can be disposed of by glycolysis, and by glycogen synthesis (in the cells which store glycogen, namely liver and muscles). [33] [35] Glucokinase, unlike hexokinase, is not inhibited by G6P. It occurs in liver ...
Glucokinase (GK) is a hexokinase isozyme, related homologously to at least three other hexokinases. [4] All of the hexokinases can mediate phosphorylation of glucose to glucose-6-phosphate (G6P), which is the first step of both glycogen synthesis and glycolysis .
The new findings suggest that eating high-fiber foods such as vegetables, beans and grains might help protect against harmful bacteria, he added. More research on fiber and health
Hexokinase can return the molecule to the glycolysis pathway by phosphorylating fructose to form fructose-6-phosphate. However, in uncontrolled diabetics that have high blood glucose - more than the glycolysis pathway can handle - the reactions mass balance ultimately favors the production of sorbitol. [6]
