Chitin in arthropods
WebChitin, the second most abundant natural polysaccharide, after cellulose, is a linear polymer composed of repeating β(1,4)-N-acetylglucosamine units (Figure 18).Chitin exists in the … WebArthropods have an exoskeleton of a tough compound called chitin. This outer shell provides the structure against which arthropod muscles pull, reduces water loss, and protects them from environmental dangers. To move inside such a rigid armor, the chitin is laid down in plates, with joints between them.

Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins. This happens in parts of the body where there is a need for rigidity or elasticity. Typically the mineral crystals, mainly calcium carbonate, are deposited amon…
