WebINTRODUCTION. Chitin is an important structural component of the cell wall of fungi and yeasts and the main carbohydrate component of arthropod exoskeletons. 1 After cellulose, it is the second most abundant biopolymer present in nature. 2 The production of chitin in the biosphere is estimated to be around 1000 billion (10 11) tons per year. 3 Chitin was … WebFor chitin the solubility parameter (δ) is 12.5, for the chitin-LiCl complex, d~11.2. Two good amide polymer solvents (a polymer solvent is a solvent with the approximately the same solubility parameter as the polymer) are dimethyl-acetamide (δ=10.8) and N-methyl pyrrolidinone (δ=11.3) [2].
