The chitinous exoskeleton of arthropods is formed by the polymerization of:
- D-glucosamine
- N-acetylglucosamine
- Lipoglycans
- 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.
