WebDec 12, 2014 · Solubility properties of chitin and chitosan are highly dependent on the number of free amino groups in the molecules. Chitin possesses a low content of amino groups. Therefore most chitins are not soluble and do not swell in common solvents; however very partially deacetylated chitin (DA 25 %) and β-chitin can be swollen in water. 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 …
