• Description: Chitin is a naturally occurring polysaccharide found in the shells of living organisms such as crabs, lobsters, tortoise, shrimps, and insects or it can be generated via fungal fermentation processes. And chitosan is a unique biobased polymer that is a derivative of chitin and forms the exoskeleton of arthropods. It is obtained by partial deacetylation of chitin using a chemical method or by enzymatic hydrolysis. In general, chitin with a degree of deacetylation of 70% or above is considered to be chitosan. Chitin is the most abundant natural amino polysaccharide. It has a similar annual yield as cellulose. Chitin is a kind of highly valuable material in biomedical applications because of its high biocompatibility, biodegradability and non-toxicity as well as its antimicrobial activity and low immunogenicity. It can be easily processed into gels, membrane, nanofibers, beads, nanoparticle, scaffold and sponges, enables its wide applications. In the tissue engineering, it can be used for manufacturing polymer scaffold to satisfy the demands of repairing, replacing, maintaining, or enhancing the function of a particular tissue or organ. In wound dressing, chitin can be used as antimicrobial reagent. In the field of drug delivery, the water-soluble carboxymethyl chitin (CMC) nanoparticle can be used as an effective carrier in drug delivery.
• Uses: Chitin, a β(1,4) polymer chain of N-acetyl-D glucosamine, is used as a substrate to identify, differentiate and characterize chitinase(s) and chitin deacetylase(s). Chitin may be used as a viscosity/thickening agent or binder. chitin (chitine) is a moisture retainer and film-forming agent. This is a naturally occurring polysaccharide found in the shells of crustaceans, such as shrimp and crab, as well as in some fungi and algae. A naturally occuring fibre found in the shells of shellfish. Used for the analysis of chitinase. lysozyme substrate.
