Sugars on the human body and the role of nutritional value

Sugar is the main physiological functions of the human body to provide the necessary energy, 1 g sugar oxidation in the body can produce 16.7 kJ (4 kcal) energy. Sugar also constitutes a heavy human tissues
To the material composition in the course of human life plays an important role.
Sugars from the diet in the human body is made of heat in the most economical method is the most important means of energy supply. Carbohydrate and protein and fat in the body's metabolism is closely related to. If the food shortage in the supply of sugar, the body will have to use the protein to meet the body's energy activities, which will affect the body's synthesis of new proteins and organizations to update the rate. When carbohydrate and protein intake along with the body, the body of nitrogen retention than when the high-protein diet alone. This is mainly because the organization of free amino acids have been re-synthesis of protein needed to consume a large amount of energy, both were taken at the same time, this part of the energy supply from sugar, a reduction of protein-induced Depletion. This phenomenon, known as the physiological role of the protein carbohydrate economy. When an adequate supply of sugar, can also prevent a large number of fat oxidation in the body and produce an excessive amount of ketones.
Sugar is an important material and human tissues, such as sugar and protein combined to form the cell membrane glycoprotein is an important component of one of the ingredients. It is also involved in a variety of human cell metabolism, human life is an indispensable material.
The main sugar in the body to glucose (blood sugar) or in the form of glycogen. Food intake or body into its own synthesis of glucose in the body needs energy.
