WebApr 19, 2024 · Crab shells are an important feedstock for chitin production. However, their highly compact structure significantly limits their use for the production of chitin under mild conditions. Here, a green and efficient approach using a natural deep eutectic solvent (NADES) to produce chitin from crab shells was developed. Its effectiveness in isolating … WebJan 26, 2024 · This critical molecular difference has major effects in the structure and properties of the chitin and chitosan (see Figure 8A). The acetyl group in chitin's macromolecular backbone provides hydrophobicity, while the remaining amino groups in chitosan are more charged. Consequently, as chitosan lacks the hydrophobic acetyl …
