Natural polysaccharides such as cellulose,\u003c\/p\u003e\u003cp\u003ehemicellulose, and starch are among the candidates from natural resources for biomass\u003c\/p\u003e\u003cp\u003epolysaccharide products including bioplastics. Although several kinds of neutral or anionic\u003c\/p\u003e\u003cp\u003epolysaccharides such as chitin, alginic acid, hyaluronic acid, heparin, and chondroitin sulfate\u003c\/p\u003e\u003cp\u003eexist in nature, natural cationic polysaccharides are quite limited. Chitin is second only to\u003c\/p\u003e\u003cp\u003ecellulose as the most natural abundant polysaccharide in the world. Chitosan, the product\u003c\/p\u003e\u003cp\u003efrom the N-deacetylatation of chitin, appears to be the only natural cationic polysaccharide.\u003c\/p\u003e\u003cp\u003eTherefore, chitin and chitosan due to their unique properties are expected to continue to offer\u003c\/p\u003e\u003cp\u003ea vast number of possible applications for not only chemical or industrial use, but also\u003c\/p\u003e\u003cp\u003ebiomedicine. The research history on chitins, one of the most major and abundant natural\u003c\/p\u003e\u003cp\u003epolysaccharides on earth, started around 1970. Since the 1980s, chitin and chitosan research\u003c\/p\u003e\u003cp\u003e(including D-glucosamine, N-acetyl-D-glucosamine, and their oligomers) has progressed\u003c\/p\u003e\u003cp\u003esignificantly over several stages in both fundamental research and industrial fields.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"MDPI AG","offers":[{"title":"Default Title","offer_id":47034999111920,"sku":"9783038421306","price":59.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783038421306_p0.jpg?v=1763712440","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783038421306","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
