Chitosan cs

Manufactured by Sinopharm
Sourced in China

Chitosan (CS) is a natural polysaccharide derived from the shells of crustaceans, such as shrimp and crab. It is a linear, cationic polymer with a structure similar to cellulose. Chitosan has unique physical and chemical properties, including biodegradability, biocompatibility, and antimicrobial activities. It is commonly used in various industrial and biomedical applications.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
