WebChitin exists in the shells of arthropods such as crabs, shrimps, and insects and is also produced by fungi and bacteria. Chitosan, the partially N-deacetylated analog of chitin, is a heteropolysaccharide consisting of d -glucosamine and N -acetyl- d -glucosamine. WebNational Center for Biotechnology Information Commercially, chitin is extracted from the shells of crabs, shrimps, shellfish and lobsters, which are major by-products of the seafood industry.
