|Chitin, Chitosan and Derivatives||Chitin and chitosan have the same chemical structure. Chitin is made up of a linear chain of acethylglucosamine groups. Chitosan is obtained by removing enough acethyl groups (CH3-CO) for the molecule to be soluble in most diluted acids.|
|Natural Product for the 21st Century||Chitin is not exactly a household word, but most are familiar with its source. It is found naturally in the shells of crustaceans, such as crab, shrimp and lobster, as well as in the exoskeleton of marine zoo-plankton, including coral and jellyfish.|
Production of Two Chitosanases from a Chitosan-Assimilating Bacterium
Chitosan, a deacetylated derivative of chitin (a linear polysaccharide consisting of b-1,4-linked N-acetylglucosamine residues), occurs only in the cell walls of fungi belonging to the order Mucorales in nature.

|Functions and Properties|
Structural and Functional Definition of the Human Chitinase Chitin-binding Domain
Chitin, a b-1,4-linked polymer of N-acetylglucosamine, is one of the most abundant biopolymers in nature. It serves a structural role in arthropods, including crustaceans and insects, as well as mollusks, nematodes, and worms.
An Enzymic method for the determination of chitin and chitosan in fungal cell walls
The free and N-acetyl glucosamine contents, serving as a measure of the amounts of chitosan and chitin respectively, were determined in the chitinase hydrolysates of the cell wall of a wild strain of Neurospora crassa.
Effect of Chitosan and its Derivatives on the Mechanical and Electrical Properties of Paper Sheets
Paper fiber is held together by hydrogen bonds. These bonds affect the distance between the separate cross-linking fibers. Water molecules play an important role in the interfiber linkage. A large excess of free water, however, causes weakness of wet strength in paper sheets and paper board.
