What is Chitin and Chitosan?
Chitin [poly(acetylglucosamine)] is one of nature’s most abundant materials as it occurs naturally in the exoskeletons of shellfish. It is a high molecular weight biopolymer which is insoluble in water. When chitin is processed by removal of acetyl groups, the molecule becomes a molecule called chitosan [poly(glucosamine-co-acetylglucosamine)].
Chitosan is a cationic polyelectolyte which is soluble in solutions of dilute organic acids. Chitosan’s long-chained and polyelectrolyte structure of chitosan molecules provides unique behavior for a variety of applications such as in water treatment, film formation, and antimicrobial activity. Additionally, the chemical makeup of chitosan provides bioactive properties such as an immune booster in plants.
