WebChitin is an integral part of the fungal cell wall and, together with β-1,3-glucan, plays a key role in maintaining cellular integrity and can confer structural rigidity during growth and morphogenesis (Corrêa et al., 2024). Chitin accounts for 10–20% of the dry weight of the cell wall of A. fumigatus and is of considerable inportance.
