Structural biology is a branch of molecular biology, biochemistry, and biophysics. Structural biology is the study of the 3D structure of biologically important molecules and macromolecules such as proteins, nucleic acids and carbohydrates. The 3D structures of these molecules generally define their function. Biomolecules are too small to see in detail even with the most advanced light microscopes. The methods that structural biologists use to determine their structures generally involve measurements on vast numbers of identical molecules at the same time.
