What Are The Characteristics Of Glucose?

Glucose is a carbohydrate and most important simple sugar metabolism. It is the primary source of fuel used by your body. One mole of glucose yields about 2870 kJ of energy
Facts
Glucose is a monosaccharide (simple carbohydrates). Glucose is available as D – (+) – glucose and D – (-) – glucose. The D – (+) – glucose form used as fuel in your body, and is also called dextrose, but L – (-) – glucose can not be used by the body as a source of energy.
Identification
Both forms of glucose having a molecular formula C6H12O6, and is sweet-tasting, white crystalline powder having melting point of 153-156 ° C (307-312 ° F). Glucose exists mostly in cyclic chair form, but may exist in the chain form

reactivity and stability
Glucose reacts violently with sodium peroxide and potassium nitrate. It is stable below 50 ° C (122 ° F).
Importance of Metabolism
The body converts other monosaccharides, such as fructose and galactose to glucose. The body can also break down the disaccharides (e.g., lactose and sucrose) and polysaccharides (such as starch) into glucose. Some fats and proteins can be converted to glucose as well. The body controls the amount of glucose in the blood using hormones. One mole of glucose yields about 2870 kJ of energy. Eating large amounts of glucose can cause excessive motility of the stomach or intestines and diarrhea.
