Chemistry, Biochemistry, and Pharmacology

Understanding the interactions between molecules—that's chemistry. And understanding the chemistry that occurs in living organisms—that's biochemistry. Understanding how medicines work in the body and finding ways to make them to work better—that's pharmacology. Studies in these areas focus on questions like:

  • How do enzymes generate cellular energy and help drive chemical reactions?
  • How are medicines processed inside the body?
  • What roles do natural substances like fats and sugars play in our bodies?
  • How does a person's genetic makeup affect how well a drug works?
  • How can we use chemistry to design new medicines?
  • Can we find new uses for existing medicines?
