Product Introduction

Chitosan Oligosaccharide (COS) is kind of oligosaccharide (degree of polymerization<20), also known as chitin oligoes. Chemical name: β-(1,4)-2-azyl-2-deoxy-D-glucan.

It is not the saccharide in common sense and derive from shrimp and crab shells. COS is not generate heat, but it has various physiological activity for applying in various field. COS is a kind of oligose and animal cellulose. COS is the unique alkaline oligosaccharide in natural world
