Chitin/chitosan enzymatic modification

Chitosan (N-deacetylated derivative of chitin), a naturally abundant mucopolysaccharide and its derivatives containing COSs were prepared by enzymatic and chemical modification. In addition, chitosan and its derivatives showed potent antioxidant activity. Moreover, chemical modification of chitosan can be easily provided with more powerful antioxidative compounds. Considering the above findings, it is expected that chitosan and its derivatives contained COSs wonld be promising candidates as potent antioxidative agents leading to their valuable use in neutracenticals and expand their applications in Biomedicine.
