Fig. 1: Schematic model of the fungal cell wall.
From: Vaccines for human fungal diseases: close but still a long way to go

This model shows the three basic components of the cell wall present in almost all fungal pathogens. Mannoproteins have polymers of mannose that decorate the proteins through O-linkages or N-linkages and are predominately found in the outer portion of cell wall. β-glucans are the most abundant constituent of the cell wall and tend to be in the middle with β-1,3-glucans forming the scaffold and β-1,6-glucans forming the branches, while chitin is found in the inner portion of the cell wall and linked to β-1,3-glucan. Other components of the cell wall in some fungi include α-glucan, galactomannan, chitosan, and melanin. In addition, the cryptococcal capsule is linked to the cell wall.
