Hexokinase (HK)
Kev piav qhia
Siv Hexokinase rau kev txiav txim siab ntawm D-glucose, D-fructose, thiab D-sorbitol hauv cov zaub mov lossis kev tshawb fawb lom.Lub enzyme kuj tseem siv rau kev soj ntsuam ntawm lwm cov saccharides uas hloov mus rau cov piam thaj los yog fructose, thiab yog li ntawd muaj txiaj ntsig zoo hauv kev soj ntsuam ntawm ntau glycosides.
Yog tias Hexokinase tau siv ua ke nrog qabzib-6-phosphate dehydrogenase (G6P-DH) * (kev soj ntsuam glucose6-phosphate tsim los ntawm Hexokinase), cov qauv yuav tsum tsis txhob muaj cov phosphate ntau npaum li G6P-DH yog kev sib tw los ntawm phosphate.
