WebChitin microfibrils are generally resistant to the deacetylases due to the presence of hydrogen bonds. Deacetylases act on the newly synthesized chitin in chitosome prior to synthesis of chitin microfibrils (Kolodziejska & Sikorski, 1999). Several biomolecules like protein, other polysaccharides, and matrix of β-glucan molecules surround the ...
