Details:
Chitosan Oligosaccharide is a mixture of oligomers of D-glucosamine. It is the only known positively charged alkaline amino oligosaccharide which is derived from rich marine biological resources (shrimp & crab shells) with enzymatic degradation. The degree of polymerization of the chitosan oligosaccharide is from 2 to 10, and the molecular weight is average 2,000.
Synonym: Chitosan Oligomers, Chitooligosaccharide
