Chitosan

Chitosan is a polycationic heteropolysaccharide contains two monosaccharides, glcnac and d-glucosamine (glcn), linked together by î²-(1â��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.liquid chitosanmost of the naturally occurring polymers are either neutral or acidic in condition includes, cellulose, dextran, pectin, alginic acid, agar but chitosan is the highly basic polysaccharide, with a nitrogen content varying between 5% and 8%, depending on the extent of deacetylation. The production of chitosan from chitin undergoes alkaline deacetylation (40â��45% sodium hydroxide, 120â°c, 1â��3 h). The degree or percentage of deacetyation is increased with increasing temperature or naoh concentration. It contains many chemical properties includes linear polyamine, reactive amino groups, reactive hydroxyl groups, chelates many transitional metal ions.
