Chitin Molecular Structure-Molecule Struture
Molecule Structure Image



Chitin is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans and insects, the radulas of mollusks and the beaks of cephalopods, including squid and octopuses. Chitin may be compared structurally to the polysaccharide cellulose and functionally to the protein keratin. Chitin has also proven useful for several medical and industrial purposes. It is used as an additive to thicken and stabilize foods and pharmaceuticals. It also acts as a binder in dyes, fabrics, and adhesives. Industrial separation membranes and ion-exchange resins can be made from chitin.
