Web#2 Composition of Exoskeleton. The second layer (procuticle) of the exoskeleton of insects is composed of chitin and sclerotin. But the exoskeleton of crustaceans contains magnesium calcite and amorphous calcium phosphate. The difference in the composition is the result of evolutionary changes related to habitat and their niche specialization.

Sclerotin is a component of the cuticle of various Arthropoda, most familiarly insects. It is formed by cross-linking members of particular classes of protein molecules, a biochemical process called sclerotization, a form of tanning in which quinones are enzymatically introduced into the cuticle, and react with terminal and lysine-related amino groups in the proteins to form strong links between t… The relative abundance of these two main components varies from approximately 50/50 to 80/20 chitin protein, with softer parts of the exoskeleton having a higher proportion of chitin. The cuticle is soft when first secreted, but it soon hardens as required, in a process of sclerotization. See more Arthropods are covered with a tough, resilient integument or exoskeleton of chitin.
