Chitin forming exoskeleton in arthropods is second most abundant carbohydrate on this earth. It is a:

Correct answer: B. Nitrogen containing structural homopolysaccharide

  • A. Storage sulphur containing polysaccharide
  • B. Nitrogen containing structural homopolysaccharide
  • C. Mucopolysaccharide
  • D. Structural oligosaccharide

Explanation

The correct answer is that chitin is a nitrogen-containing structural homopolysaccharide. Chitin is a long-chain polymer of N-acetylglucosamine, a derivative of glucose, and it is used primarily for structural purposes in the exoskeletons of arthropods. The other options are incorrect because they do not accurately describe the composition or function of chitin: it is not a storage polysaccharide, it does not contain sulfur, it is not a mucopolysaccharide, and it is not an oligosaccharide.

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
