Chitin is a cellulose-like biopolymer distributed widely in nature. Chitosan is the deacetylated product of chitin. The chemical structure of chitin and chitosan can be seen to be very similar to that of cellulose, the difference being that OH group of each glucose unit in cellulose is substituted by an acetylated amino group (-NHCOCH3) in chitin and an amino group (-NH2) in chitosan.
