Chitin (C8H13O5N)n (/ˈkaɪtɪn/ KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose. Chitin is probably the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. It is a primary component of cell walls in fungi (especially basidiomycetes and filamentous fun… WebChitin is a copolymer of N -acetyl-glucosamine and N -glucosamine units randomly or block distributed throughout the biopolymer chain, depending on the processing method used to derive the biopolymer ( Khor and Lim, 2003 ). The biopolymer is termed chitin if the number of N -acetyl-glucosamine units is higher than 50%.
