Electron density puzzles provide real experimental data about the folded shape of the protein. X-ray crystallography or electron microscopy (EM) experiments produce a density cloud in the shape of the folded protein. Sometimes the density is crisp and clear, but other times it can be fuzzy or hard to interpret.
