25 Ιαν 2017 · Biological crystallography, the main method of structural biology, which is the branch of biology that studies the structure and spatial organization in biological macromolecules, is based on the study of X-ray diffraction by crystals of macromolecules.
24 Δεκ 2022 · X-ray diffraction utilizes x-ray beams targeted to hit crystallized matter and generates a diffraction pattern. Data collected using this method undergo a systematic analytical process that employes mathematical models and computer algorithms to obtain the final 3D atom model of a matter.
X-ray diffraction, phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X-rays. The atomic planes of the crystal act on the X-rays in exactly the same manner as does a uniformly ruled diffraction.
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering , when there is no change in the energy of the waves.
X-ray diffraction is used to determine the identity of crystalline solids based on their atomic structure. Because of the different geometric configurations, the polymorphs diffract X-rays at different angles. X-ray diffraction can be performed in wide-angle X-ray scattering (WAXS) and small-angle X-ray scattering (SAXS).
The results of X-ray diffraction studies of both small and large molecules of biological interest have greatly enhanced our understanding of many biochemical processes such as enzyme mechanisms, nucleic acid flexibility and virus assembly.
