The chitinous exoskeleton of arthropods is formed by the polymerisation of:
Correct answer: A. N-acetyl glucosamine
- A. N-acetyl glucosamine
- B. Lipoglycans
- C. Keratin sulfate and chondroitin sulfate
- D. D -glucosamine
Explanation
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) linkages. The chitinous exoskeleton provides strength and elasticity to arthropods.
