chitin The organic matrix of the hard parts of the exoskeleton of insects and crustaceans, and present in small amounts in mushrooms. It is an insoluble and indigestible
non‐starch polysaccharide, similar to
cellulose, but composed of
N‐acetylglucosamine units rather than glucose. Partial deacetylation results in the formation of
chitosans.
