Chitin is second only to cellulose from its abundance on Earth. The key difference between cellulose and chitin is that cellulose is the significant structural polymer in the primary cell walls of the plant cells while chitin is the main structural polymer found in the fungal cell wall.

When comparing chitin and cellulose The main difference is?

The main difference between chitin and cellulose is that the chitin is a polymer of N-acetyl-D-glucosamine whereas the cellulose is a polymer of D-glucose.

How is the structure of cellulose different from that of chitin?

How is the structure of cellulose different from that of chitin? Cellulose is made of β-glucose monomers linked in an alternating chain, whereas chitin is made of N-acetylglucosamine monomers (NAG) linked in an alternating chain.
