• B. It is a homopolysccharide
• C. It is a constituent of arthropod exoskeleton and fungal cell wall
• D. It is the second most abundant carbohydrate on eart

Answer 1

Answer: (A)

Chitin is the second most abundant polysaccharide (after cellulose). Chitin is not a storage polysaccharide rather it is a structural homopolysaccharide, formed of Nacetylglucosamine (NAG) monomers joined together by $\beta$- 1, 4 linkages. Also, it forms the structural component of fungal walls and exoskeleton of arthropods
