Structural Polysaccharides. Chitin is a structural component of arthropod exoskeletons, fungi cell walls, mollusk shells, and fish scales. This simply means that it is made up of repeating units of the same monosaccharide, which is N-acetylglucosamine in this case. Between chitin and cellulose, both polysaccharides made of glucose monosaccharides, hundreds of billions of tons are created by living organisms every year. Chitin definition, a nitrogen-containing polysaccharide, related chemically to cellulose, that forms a semitransparent horny substance and is a principal constituent of the exoskeleton, or outer covering, of insects, crustaceans, and arachnids. It also forms the cell wall of mushrooms and the beaks of squid and octopi. Therefore, being considered as a superior material for a sustainable future of industrial development, chitin perfectly meets up . A polysaccharide can be mixed with any number of other components to create tissues that are more rigid, less rigid, or even materials with special properties. Chitin is a modified polysaccharide made of N-acetyl glucosamine units. Introduction. The exoskeleton of insects is also chitinous, and the cell walls of certain fungi contain this substance. The repeating unit of the polysaccharide consists of two residues held together by β (1 - > 4) glycosidic links, as was the case in cellulose and chitin. Cellulose is found.. Chitin is a large, structural linear polysaccharide made from chains of N-acetyl-D-glucosamine [2-(acetylamino)-2-deoxy-D-glucose)] [Figure 1]. Chitin is the principle component of the hard exoskeletons of nearly a million species of arthropods, insects, lobsters and crabs. Glycogen and cellulose are two other homopolysaccharides. Three Main Polysaccharides Starch ─ an energy source obtained from plants.
