Unit definition:
One Unit of hexokinase activity is defined as the amount of enzyme required to produce one μmole of NADH from NAD+ in the presence of D-glucose and glucose-6-phosphate dehydrogenase at pH 7.4 and 25oC. 

One Unit of Glucose-6-phosphate dehydrogenase activity is the amount of enzyme required to convert one μmole of glucose-6-phosphate to 6-phosphogluconate per minute, in the presence of NADP+ at pH 7.4 and 25oC. 

Catalyses the reaction:
ATP + D-hexose = ADP + D-hexose 6-phosphate

Phopshorylates D-glucose, D-mannose, D-fructose, sorbitol and D-glucosamine.

Glucose-6-phosphate dehydrogenase:
Catalyses the reaction:
D-glucose 6-phosphate + NADP+ = 6-phospho-D-glucono-1,5-lactone + NADPH + H+

Applications for the measurement of glucose and other hexoses in carbohydrate research and in the food and feeds, fermentation, wine, beverage and dairy industries.
