D-mannose is an organic compound with molecular formula of C6H12O6, molecular weight of 180.156, colorless or white crystalline powder. It plays an important role in the process of human metabolism, especially in the glycosylation of specific proteins.

D-mannose is a component of many polysaccharides. It exists in the peel of some plants in free state, such as citrus peel, a small amount of free mannose in peach, apple and other fruits, and D-mannose in Ivory palm, yeast, red algae, serum globulin, ovomucoid protein and Mycobacterium tuberculosis.

Mannose is white crystal or crystalline powder, sweet with bitter taste. It is soluble in water and slightly soluble in ethanol. D-mannose can be used as an additive in beverage and food, and it is also a good sweetener at present. So what kind of role and effect does it play in our life?

D-mannose has many uses. First of all, for human health, D-mannose is the only glyconutrient used in clinic. It exists in human body fluids and tissues, especially in human nerve, skin and other tissues, and can participate in immune regulation. Many diseases are caused by the lack of enzymes in mannose glycosylation. Therefore, it is very important for human health.

Its physiological effects in human body are as follows

1) Regulating the immune system

2) There are four kinds of receptors on the surface of macrophages that can capture antigens, all of which contain mannose

3) Increase wound healing

4) Anti inflammatory effect

5) Inhibit tumor growth and metastasis, increase cancer survival rate

6) It can avoid some bacterial infections, such as urinary tract infection

Other uses: low calorie sweetener; Anti sticking agent for gum and candy; Nutritional supplements and tissue improvers; Moisturizer.
