Science Education: Structural Biology

Protein structuresUnderstanding the shapes of biological molecules to learn more about how they function and interact—that's structural biology. Studies in structural biology focus on questions like:

  • Why does a protein's shape matter?
  • How can misshapen molecules make us sick?
  • How can we visualize the structural details of large and complex molecules?

Follow the links below to learn more about structural biology,including recent developments, and read profiles of researchers working in this field.
