Chitin is found in which combination of taxa

WebJul 28, 2015 · Chitin is a polymer of N-acetylglucosamine, linked with β -1,4-glycosidic bonds. It is a major portion of cell walls of fungi, exoskeleton of insects, and crustacean shells. Despite its abundance, chitin does not accumulate in the environment due to presence of chitinolytic enzymes known as “chitinases.”
