NEET BIOLOGY

Detailed explanation-1: -The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins. As the components of the fungal cell wall are not present in humans, this structure is an excellent target for antifungal therapy.

Detailed explanation-2: -Chitin and chitosan are two related polysaccharides that provide important structural stability to fungal cell walls. Often embedded deeply within the cell wall structure, these molecules anchor other components at the cell surface.

Detailed explanation-3: -Chitin structure and diversity in fungi. Chitin is a (1, 4)-homopolymer of N-acetylglucosamine that folds in an anti-parallel manner forming intra-chain hydrogen bonds. Chitin chains are cross-linked covalently to (1, 3)-glucan (green) to form the inner skeleton of most fungi.
