Chitosan CAS Number

Chitosan is a polycationic linear polysaccharide derived from chitin. As a versatile, biocompatible, and biodegradable biomaterial, it displays broad antibacterial, antifungal, antioxidant, and antitumor activities. Its positively charged amino groups interact with negatively charged cell membrane components, disrupting microbial membrane integrity and inhibiting cell growth. Furthermore, chitosan regulates oxidative stress responses and suppresses tumor cell viability, making it a valuable agent in biomedical research. ^[1]
