Chitin and chitosan. Part III. Some aspects of biodegradation and bioactivity

A review on chitin and chitosan continues with the introduction into their chemistry. This part discusses some aspects of biodegradability and bioactivity of chitosan, chitin and products of their depolymerization. This paper describes the role of enzymes having the susceptibility for chitinous polymer degradation in nature and the hypothetical mechanisms of biological activity of chitosan and its oligomers.
