I am going to explain the properties of hexokinase IV and it's properties that make it important for the maintainance of stable blood sugar level.
Hexokinase as well as Hexokinase IV all phosphorylate the glucose at C-6, Because Hexokinase IV has a low affinity with glucose and it is expressed in the liver,so it does have a way of maintaining blood sugar level.
When the blood glucose is low generally,it isn't saturated or working,but when the blood glucose gets high,it becomes transactivated and the activity of glucose 6 phosphatase results in low blood glucose.
Therefore,the most important activity of
Hexokinase IV is the regulation of blood glucose levels.
