Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. This extremely versatile molecule can form solid structures on its own as in insect wings, or can combine with other components like calcium carbonate to make even stronger substances like the shell of a clam.
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. Chitin and cellulose are both made from glucose monomers, while keratin is a fibrous protein.
