WebChitin is a structural polysaccharide found in the species such as yeast, fungi, insects, and marine invertebrates. Structurally, Chitin is a homopolymer of N-acetyl glucosamine with β- (1,4) linkages, while chitosan is deacetylated chitin. Chitin is produced commercially from shellfish waste through chemical treatment. WebChitosan is made from chitin by deacetylation. Chitin is naturally found in the exoskeletons of arthropods and in fungi. It is the second most abundant natural polymer on earth after cellulose and is structurally very similar to cellulose. However, each subunit of chitin contains an acetyl amine group which allows additional hydrogen bonding ...
