1. Molecular weight difference: Chitosan oligosaccharide is a new product of chitosan treated by special biological enzyme technology, with a molecular weight below 3000 Da; Chitosan is a partially deacetylated product of chitin, with a molecular weight of 500000 to 1000000.
2. Difference in solubility: chitooligosaccharide has low molecular weight and can be completely soluble in water; Chitosan can only be dissolved in dilute acid solution. Gold chitosan high-density chitosan indicates that the enhancement of water solubility is an important factor affecting some physiological activities of chitosan oligosaccharides. Only when it is soluble in water, it can be absorbed and utilized by organisms, showing biological activity. Therefore, chitosan oligosaccharides are more easily absorbed by humans, animals and plants.
3. Functional differences: Chitosan oligosaccharides with molecular weight below 2000 Da exhibit unique physiological activities and functions: improve the function of macrophages; Inhibit the growth and metastasis of tumor cells; Lower cholesterol and blood lipid; Antibacterial, bacteriostatic and significant moisture absorption capacity.
Gold chitosan high-density chitosan indicates that chitosan oligosaccharide with molecular weight less than 5000Da can hinder the growth and reproduction of pathogenic bacteria, promote protein synthesis, activate plant cells, and thus promote the rapid growth of plants.
The multiple functions of chitosan oligosaccharide indicate that it is an alternative in the oligosaccharide family. Chitosan oligosaccharide is the only alkaline and positively charged oligosaccharide found in the oligosaccharide family. This feature also determines that it is the only oligosaccharide that can be absorbed by the intestinal tract and enter the blood circulation, and its access to various parts of the body through the blood circulation is the basis for its many other biological functions.
Chitosan oligosaccharide is not digested by digestive enzymes on the premise that it is absorbed by the intestinal tract. Chitosan oligosaccharide is composed of glucosamine β- 1,4-glycosidic bond, and digestive enzymes in human gastrointestinal tract mainly act on α- 1,4-glycosidic bond, so chitosan oligosaccharide can maintain structural integrity in gastrointestinal tract.
