Chitosan is a biopolymer derived from chitin, a natural polymer found in the shells of crustaceans such as shrimp, crabs, and lobsters. It is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitosan has a range of applications due to its unique physical and chemical properties, including its ability to form films, gels, and beads, and its biocompatibility.
