The structure of chitin is most similar to that of cellulose. Its function is most similar to that of keratin. Chitin is a structural component of arthropod exoskeletons, fungi cell walls, mollusk shells, and fish scales. A typical arthropod exoskeleton is a multi-layered structure with four functional regions: epicuticle, procuticle, epidermis and basement membrane. Of these, the epicuticle is a multi-layered external barrier that, especially in terrestrial arthropods, acts as a barrier against desiccation. The strength of the exoskeleton is provided by the underlying procuticle, which is in turn secreted …
