The chitinous exoskeleton of arthropods is formed by the polymerisation of
  1. A
    N - acetyl glucosamine
  2. B
    lipoglycans
  3. C
    keratin sulphate and chondrotin sulphate

View written solutionFree

Correct answer: A

Chitin is a structural polysaccharide that constitutes the exoskeleton of arthropods. It is a complex carbohydrate in which N-acetyl glucosamine monomers are joined together by (1, 4) β\beta β-linkages. Chitinous exoskeleton provides strength and elasticity to arthropods.
