glucosamine

Chitosan is a nontoxic, biodegradable and a high mass linear polymer (2-amino-2-deoxy-β-D-glucan) . It is a deacetylated form of chitin and was first discovered by Rouget, 1859, He observed that by the manipulation in the compound of chitin through chemical and temperature treatments it become soluble. Act as a shell component of crustaceans like shrimp and crab, skeletal invertebrates and cell wall element of fungi and insects. It has biocompatibility, physical stability and processability. Chitosan be described as polycationic heteropolysaccharide contains two monosaccharides, GlcNAc and D-glucosamine (GlcN), linked together by β-(1→4) glycosidic bonds. The reaction of chitosan is more versatile compared to cellulose, due to presence of NH2 group. Chitosan is also available in liquid form i.e.
