The chitinous exoskeleton of arthropods is formed by the polymerization of:
  1. D-glucosamine
  2. N-acetylglucosamine
  3. Lipoglycans
  4. Keratin sulphate and chondroitin sulphate

Solution

The exoskeleton of Arthropods is made up of chitin. Chitin is a mucopolysaccharide made up of monomeric glucose derivative N-acetylglucosamine. It is found in the cell wall of fungi and also in the exoskeleton of crustaceans.
