Chitin is deacetylated under alkaline conditions and is called chitosan when a certain degree of deacetylation is reached. Therefore, chitosan is also known as deacetylated chitosan. Chitosan is a natural linear polysaccharide composed of multiple N-acetyl-D-glucosamine monomers connected by β-1,4-glycosidic bonds. The structure is shown in Figure 1. Chitosan is widely present in the shells…
