Questions and Answers

Which of the following is a major focus of the Natural Products Chemistry course?

  • Studying the properties of inorganic compounds
  • Investigating the use of chemical reagents in organic synthesis
  • Exploring the synthesis of synthetic chemicals
  • Reviewing the major classes of natural compounds (correct)

How are synthetic chemicals different from natural products?

  • Synthetic chemicals are purely organic, while natural products may contain inorganic elements.
  • Synthetic chemicals are less selective than natural products.
  • Synthetic chemicals tend to change cellular structures, while natural products are made by enzymes. (correct)
  • Synthetic chemicals are derived from plants, while natural products are obtained from cells of organisms.

What makes the biosynthesis of natural products interesting?

  • It leads to the formation of purely organic compounds
  • It is more selective and produced by enzymes (correct)
  • It involves extraction, isolation, and purification techniques
  • It is derived from plants and animals
