Glucose is a six-carbon sugar containing an aldehyde group, with the molecular formula C6H12O6, and is the most important monosaccharide in living organisms. Its main function is to provide the energy required for the physiological activities of the body. It is known that 1 mol of glucose is completely oxidized to release energy of 2870 kJ (686 kCal), accounting for 70% to 80% of the total energy required by the body. In addition to energy supply, glucose is also a carbon source for human biosynthesis and an important precursor for lipid synthesis; it also provides the backbone for the synthesis of essential amino acids in the body. Under normal conditions, the concentration of glucose (blood glucose) in the blood is in dynamic equilibrium, and the body has a set of mechanisms for regulating blood glucose concentration by nerves, liver, hormones and kidneys. The normal fasting blood glucose concentration is 3.8-6.1mmol/L.

Glucose (also known as dextrose) is a monosaccharide that can be directly absorbed by the body and is the main source of nutrients and energy for the body, and can directly participate in metabolic processes in the human body. In the digestive tract, glucose is more readily absorbed than any other monosaccharide and can be directly utilized by human tissues after absorption. Oligosaccharides (e.g. sucrose) and polysaccharides (e.g. starch) ingested by the body must also be converted to glucose before they can be absorbed and utilized by human tissues. Glucose can be oxidized to carbon dioxide and water in the human body. 17.1 KJ of heat is released per gram of glucose oxidized to carbon dioxide and water, and 50% of the energy required by humans and animals comes from glucose.
