Chitin Chemical Properties,Uses,Production
Description
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.
Chemical Properties
Chitin is a colorless, crystalline or amorphous powder that is insoluble in water, organic solvents, dilute acids, and alkalis. It dissolves in concentrated mineral acids with simultaneous degradation of the polymer. Although chitosan is insoluble in water, it does dissolve in aqueous organic acids, for example, acetic and formic acids, as well as inorganic acids. Chitin and chitosan preparation can vary due to the source, with compositional differences. Similarly, the physicochemical characteristics of chitin and chitosan differ between crustacean species and preparation methods. Several studies have clearly demonstrated the specific characteristics of these products. The Mw and degree of deacetylation (DD) vary with process conditions. The physicochemical characteristics of chitin and chitosan influence their functional properties. Mw and DD vary with process conditions or different extraction methods. Chitosan's application depends on physical, biological, and chemical properties and chitosan depends on two parameters, such as DD and Mw.
Uses
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. It is also a naturally occuring fibre found in the shells of shellfish. Used for the analysis of chitinase. lysozyme substrate.
Definition
ChEBI: Chitin is a polysaccharide comprisingchains of N-acetyl-d-glucosamine,a derivative of glucose. Chitin isstructurally very similar to celluloseand serves to strengthen the supportingstructures of various invertebrates. It is the second most abundant biopolymer on earth, found especially in insects and fungi.
Agricultural Uses
Chitin is a polysaccharidec omprising chains of N-acetyl- D-glucosamine, a derivative of glucose, linked byβ-1,4 bonds and containing about 77 nitrogen atoms. It may be visualized as cellulose in which the hydroxyl groups on the second carbon are replaced by -NHCOCH3 groups Chitin is structurally very similar to cellulose and serves to strengthen various invertebrates. It offers resistance to chemicals and is present in the cell wall of some fungi as well as in the exoskeleton of insects.
