WebWhat is chitin where is it found what is its major function? Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium.

WebInsects have exoskeletons made of a substance called chitin. The exoskeletons of crabs, lobsters, shrimp, spiders, ticks, mites, scorpions, and related animals are also made of chitin. While exoskeletons are hard and stiff, they also have joints, or bendable sections. These joints allow the animals to move easily. WebFunction of Chitin Chitin, like cellulose and keratin, is a structural polymer. Made from smaller monomers, or monosaccharides, structural polymers form strong fibers. When secreted inside or outside of cells in an organized way, the fibers form weak bonds between each other. This adds strength to the entire structure.
