Major components of fungal cell walls.

Fungal cell wall components	Structure composition	Location
Chitin	Homopolymer of N-Acetylglucosamine that provides structural stability	Inner portion of cell wall, adjacent to the plasma membrane
Chitosan	Deacetylated chitin	Inner portion of cell wall, intermingled with chitin
β-glucan	Homopolymers of glucose with β-1,3-glucans forming the scaffold and β-1,6-glucans forming the branches	Middle portion of cell wall, between chitin and mannans
Mannoprotein	Mannose chains of varying lengths and configurations added to fungal proteins via N-linkages or O-linkages	From anchorage in plasma membrane to outer portion of cell wall
