The central nervous system is almost entirely dependent on the supply of blood sugar for energy, and glycosuria may occur once blood sugar rises to 80 mg %.
Commercially, glucose is produced by starch hydrolysis, and in the 1960s, microbial enzymes were used to produce glucose. This is a major innovation and has obvious advantages over acid hydrolysis. In the production of raw materials do not need to be refined, do not need acid, pressure resistant equipment, and the sugar liquid is not bitter, high sugar production rate.
Glucose is used in medicine primarily as an injectable nutrient (glucose injection).
In the food industry, glucose can be processed by isomerase to produce fructose, especially high fructose syrup containing 42% fructose, its sweetness is the same as sucrose, has become an important product in the sugar industry.
Glucose is an indispensable nutrient for metabolism in the body. The heat released by its oxidation reaction is an important source of energy for human life activities. It can be used directly in food and medicine industry, as a reducing agent in dyeing and leather industry, and glucose is commonly used as a reducing agent in mirror industry and silver plating process of hot water bottle. The industry also uses glucose as raw material to synthesize vitamin C(ascorbic acid).
