Question

Describe the methods of crystallization of proteins and explain the role of crystals in X-ray diffraction.

Answer 1

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.

X-ray diffraction is now a common technique for the study of crystal structures and atomic spacing. X-ray diffraction is based on constructive interference of monochromatic X-rays and a crystalline sample. ... A key component of all diffraction is the angle between the incident and diffracted rays.
