LIN-COS is Chitosan Oligosaccharide, also known as chitosan oligosaccharide and oligochitosan, is a kind of polymerization degree obtained by degrading chitosan by special biological enzyme technology The oligosaccharide product with a molecular weight of ≤3200Da is a low molecular weight product with good water solubility, large functional effect and high biological activity. It has higher solubility than chitosan, is completely soluble in water, and is easily absorbed and utilized by organisms. It has 14 times of its function as chitosan.
Chitooligosaccharides are the only positively charged cationic basic aminooligosaccharides in nature and are animal cellulose.
