Chitin, a β-(1→4)-linked N-acetyl-β-d-D-glucosamine polysac-charide, is a structural component in the exoskeletones or cell walls of arthro-pods, nematodes and fungi. Chitin is highly crystalline and has been shown to exist in three polymorphic forms: α(the most common with antiparallel chain alignment), β(parallel chain alignment) and γ(the least common of two parallel alternate with one antiparallel chain). Chitin can be easily deacetylated into chitosan whose primary amine groups exhibit cationic polyelectrolyte behavior in acidic aqueous medium as well as mucoadhesivety, antibacterial and anti-fungal biological activities desirable for many applications. Therefore, the present study contrives to realize water-soluble chitosan with high biological activity and high purity, one that is suitable for biomedical and life sciences applications (such as harmful algae species, oral absorption of wsc, handsheet paper, reactive oxygen species, and drug delivery tools). |
