In your own words, what is the definition for Chitin?

what purpose does chitin serve?

Chitin is a fibrous material made up of polysaccharides that is found in the exoskeletons of arthropods and the cell walls of fungus. Chitin is an important biopolymer found in nature. Fungi, arthropods, and nematodes are the principal producers. In insects, it acts as a scaffold, supporting the epidermis and trachea cuticles, as well as the peritrophic matrices that line the gut epithelium.
