Biodegradation of chitosan
WebThe biodegradation of chitosan leads to the formation of non-toxic oligosaccharides of variable length. These oligosaccharides can be incorporated in metabolic pathways or be further excreted [38]. The degradation rate of chitosan is mainly related to its degree of deacetylation, but also to the distribution of N-acetyl WebApr 14, 2024 · Carboxymethyl chitosan (CMCS) is an important, water-solution derivative of chitosan, which contains cationic and anionic groups. CMCS is widely used in drug delivery and wound treatment because of its good biocompatibility, nontoxicity, and biodegradability [ …
