る物質である。[Effect] The shells of crustaceans such as crabs and shrimps and the outer skins of arthropods contain a substance called chitin that forms a complex with protein and calcium carbonate. Chitosan is obtained by hydrolyzing chitin. Chitosan is a linear polysaccharide in which 2-amino-2-dioxy-D-glucose (D-glucosamine) is linked with β-(1→4) bonds. Chitin and chitosan have almost no toxicity concerns for humans and animals, are highly biocompatible, and are biodegradable, so they are used in medical and pharmaceutical applications such as wound healing agents, wound dressings after skin abrasion, and surgical threads. It is a substance for which applied research is actively being conducted in the field.
