Chitin

Chitin is a homopolymer consisting of β-[1-4] linked N-acetyl-D-glucosamine. Easily obtained, abundant in nature and naturally renewable, this polymer is in the second place after cellulose.

Chitosan

Chitosan is a cationic biopolymer comprising randomly dispersed presence of high molecular weight consisting of alkaline N-deacetylation (by deacetylation and generally A-units in chains GICNAC [β-1,4-2-acetemido-2-deoxy -β-D-glucopyranose] and D-units GIC [β(1-4}-2-amino-2deoxy-β-D glucopyranose].

Chitin’s Chemical Obtain

Chitin is produced with a thermochemical process from shrimp shells. Also, biological processes using microorganisms for demineralization and deproteinization have been recommended alternative for these chemical processes with costly and non-eco friendly nature.
