Chitosan is also called chitosan oligosaccharide and oligosaccharide. It is a oligosaccharide product with a polymerization degree of 2~20 with a molecular weight of less than 3200Da, which has been degraded by a special bioenzyme technology (also reported using chemical degradation and microwave degradation). The molecular weight of chitosan is less than 3200Da. It is a good water soluble, functional and biological activity. Low molecular weight products with high sex. It has a high solubility in chitosan, all soluble in water, easy to be absorbed by the organism and many other unique functions, which is 14 times the effect of chitosan.

Chitosan oligosaccharides are the only cationic amino acid oligosaccharides with positive charge in nature, and they are animal cellulose. Chitosan oligosaccharide is a small molecule oligosaccharide with amino from the chitosan derived from shrimp and crab shell. It is a sugar chain with a polymerization degree of 2-20.

The function of chitosan in gold shell pharmaceutical industry is analyzed. The Japanese and European and American medical circles put the chitosan oligosaccharides as the "sixth life elements" after the five vital elements of protein, fat, carbohydrates, vitamins and minerals. Scientific research has proved that chitosan oligosaccharide has the overall regulation function of the body, and its function can be summed up as "one fill, three drops, three tones, three suppression, three increase and four row".

A supplement: the essential element of life that is necessary for the human body.

Three drops: lowering blood fat, lowering blood sugar and lowering blood pressure.
