A tough, semitransparent, nitrogenous polysaccharide that forms the principal component of the exoskeletons of arthropods like crustaceans and insects.

Etymology

Derived from the Greek word 'khiton', meaning 'tunic' or 'frock', which described a type of garment; it was later adopted into science to describe the protective outer covering of animals.
