Chitin and Chitosan: Structure, Properties and Applications
Chitin and chitosan are the most abundant natural amino polysaccharide that are non-toxic, biodegradable and biocompatible. They have become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields. They are biopolymers having immense structural possibilities for chemical and mechanical modifications to generate novel pro...
متن کاملChitin and chitosan: Chemistry, properties and applications
Chitin and chitosan are considerably versatile and promising biomaterials. The deacetylated chitin derivative, chitosan is more useful and interesting bioactive polymer. Despite its biodegradability, it has many reactive amino side groups, which offer possibilities of chemical modifications, formation of a large variety of useful derivatives that are commercially available or can be made availa...
متن کاملFunctional Characterization of Chitin and Chitosan
Chitin and its deacetylated derivative chitosan are natural polymers composed of randomly distributed -(1-4)linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitin is insoluble in aqueous media while chitosan is soluble in acidic conditions due to the free protonable amino groups present in the D-glucosamine units. Due to their natural origin, both chitin a...
متن کاملChemically modified chitin and chitosan as biomaterials
Recent studies of the chemical modification of chitin and chitosan are discussed from the viewpoint of biomedical applications. Special emphasis is placed on the role of individual functional groups in applications of modified chitosan. The modifications discussed here include chitosan attached to sugars, dendrimers, cyclodextrins, crown ethers, and glass beads. Among these derivatives, sugar-m...
