Function of chitin
WebChitin is a polymer of β (1,4)-linked N-acetylglucosamine, which is the critical constituent of arthropod exoskeletons (cuticle) and the peritrophic membrane (PM) in midgut [13, 14]. The tough and durable exoskeleton provides physical support and protects insects from external damage, which also restricts the growth of insects [15].
