Burning 1 gram of sugar yields 4% of calories. Sugars are compounds that contain carbon, hydrogen, and oxygen.
Carbohydrates are found in different forms; Example: Single-priced sugars or monosaccharides, such as glucose and fructose. Double-priced sugars (die-cakes), such as sucrose. And some of the prices of sugars (polysaccharides) such as cellulose.
In different foods, the size and type of sugars vary; Example: Fructose is present in fruit, lactose is present in milk sugar, and sucrose is present in sugarcane and bean sugar, and glucose is present in sweetened beverages.
The sugars are first broken down in the glucose series cell, and then to a degree of chemical interaction, which eventually (due to glycolysis) turns into pyruvic acid. If glucose burns in the presence of oxygen. Thermal or optical energy is generated. As a result, H2O and CO2 are formed.
Starch: Starch is the source of glucose storage. In the cell, starch molecules are located inside the spherical shape of the grains, which is called Amiloplastide or starch grains.
Cellulose: An enzyme in the human body that can break down cellulose and release glucose molecules. Does not exist. Because of this, cellulose in food is of little value to humans.
