WebJan 31, 2024 · We use protein crystallography to determine, experimentally, the structure of proteins. The method applies to other macromolecules, such as nucleic acid and viruses. Accurate structures … WebIntroduction to Crystallography Amorphous solids are homogeneous and isotropic because there is no long range order or periodicity in their internal atomic arrangement. By contrast, the crystalline state is characterised by a regular arrange-ment of atoms over large distances. Crystals are therefore anisotropic – their properties vary with ...
