Chitin

Structural description

Chitin, the second most abundant natural biopolymer, is an unbranched chain of β(1-4) N-acetyl-D-glucosamine units. It is present in the cell walls of fungi and is the principal component of arthropod and lower animal exoskeletons (insect, crab, and shrimp shells…).

Chitin is analogous in chemical structure to cellulose and it may be regarded as a derivative of cellulose, in which the hydroxyl groups of the second carbon of each glucose unit have been replaced with acetamido (-NH(C=O)-CH3) groups. The degree of acetylation (DA) is generally over 90%.

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).
