Molecular Structures

Understanding 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.

  • Cool Images: The Hidden Beauty of Plants
    For plants, beauty is more than just “skin deep.” Researchers have taken images of plants’ insides, from stem cells to pollen grains, and revealed stunning structures.
  • Twisting and Turning: Unraveling What Causes Asymmetry
    Chirality is a type of asymmetry where something can’t overlap with its mirror image, like our hands. Michael Ostap, Ph.D., is researching what causes chirality on a molecular level to better understand embryonic development and how it can go wrong.
  • PECASE Honoree Sohini Ramachandran Studies the Genetic Foundations of Traits in Diverse Populations
    NIGMS grantee and presidential award recipient Sohini Ramachandran, Ph.D., is challenging our understanding of genetic variation among human populations. In our latest blog post, she discusses her research on how the genetic composition of traits and diseases varies among populations, the value of statistical and computational work in human genetics, and what this all means for patient treatment.
  • Revealing a Piece of Cilia’s Puzzle
    Cilia, hairlike projections on the surface of most human cells, are complex molecular machines that assist in moving fluids through the body and detecting environmental changes. Researchers recently mapped the full atomic structure of one of cilia’s key components, the doublet microtubule, which is essential for cilia's proper function.
