WebChitin ( C 8 H 13 O 5 N) 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. [1] WebAbstract. Because of its rigidity, the wall maintains the shape of the fungal hypha and various arguments have indicated chitin microfibrils embedded in an amorphous matrix as the major polymeric assemblage conferring rigidity to the wall (Bartnicki-Garcia 1973; Burnett 1979; Gooday and Trinci 1980; Wessels and Sietsma 1981).
