CHEM 230AMethods of Structural Molecular Biology: X-Ray Crystallography and Electron Microscopy
Chemistry and Biochemistry · 4 units · Graduate courses (200-299)
Methods for structure determination of biomacromolecules—proteins and nucleic acids—focusing on X-ray crystallography, cryo-EM imaging, and electron diffraction. Covers mathematical and computational methods used to obtain atomic structural models of biomolecules. Key physical principles include scattering phenomena, interference and diffraction, symmetry, Fourier transforms, and atomic interpretation of molecular structures in three-dimensions.
