Carbohydrates serve various functions in different animals. Arthropods (insects, crustaceans, and others) have an outer skeleton, called the exoskeleton, which protects their internal body parts (as seen in the bee in Figure 8). This exoskeleton is made of the biological macromolecule chitin, which is a polysaccharide-containing nitrogen.Compared with chitinous exoskeleton material, resilin is very soft and elastic (e.g. Weis-Fogh 1961; Andersen and Weis-Fogh 1964).
