Chitosan

Structural description

Chitosan is obtained by removing the acetyl groups (CH3-CO-) of the chitin. This process, called deacetylation, releases amine groups (NH2) and gives the chitosan a cationic characteristic. The degree of acetylation is generally lower than 20%.

Activities and Uses

Chitin and chitosan have been proven useful for several medical and industrial purposes (Kumar et al., 2000. Reactive and Functional Polymers, 46, 1-27). Many of the biological activities reported for Chitin/Chitosan are surrounding the fields of as antimicrobial, anticancer, antioxidant, and immunostimulant effects depending on their physico-chemical properties (Se-Kwon Kim et al., 2005. Carbohydrate Polymers 62, 357–368).
