electron density mapping

Electron density mapping is a technique used to visualize the locations of electrons within a crystal structure of a molecule, such as a protein. By analyzing how X-rays scatter when they pass through the crystal, scientists create a 3D map that shows regions of high and low electron density. These regions indicate where atoms are likely to be positioned, helping researchers determine the precise arrangement of atoms in the molecule. This process is essential for understanding molecular structure and function at an atomic level.
