X-Ray Crystallography UCLA. X-Ray Crystallography uses the uniformity of light diffraction of crystals to determine the structure of a molecule or atom. Then they use an X-ray beam to “hit” the crystallized molecule. The electrons surrounding the molecule diffract as the X-rays hit them. This forms a pattern, this type of pattern is called the X-ray diffraction pattern., Research and Reviews: Journal of Dairy Science and Technology Volume 2, Issue 1, ISSN: 2319-3409 _____ X-Ray Crystallography and Its Applications in Dairy Science: A Review Kamal Gandhi*, Anil Kumar, Saurabh Gosewade, Ravinder Kaushik, Darshan Lal Dairy Chemistry Division, National Dairy Research Institute, Karnal, Haryana, India, 132001 Abstract X-ray crystallography (XRC) is ….

X-ray crystallography of biological molecules took off with Dorothy Crowfoot Hodgkin, who solved the structures of cholesterol (1937), penicillin (1946) and vitamin B 12 (1956), for which she was awarded the Nobel Prize in Chemistry in 1964. In 1969, she succeeded in solving the structure of insulin, on which she worked for over thirty years. X-ray crystallography is a tool used for determining the atomic and molecular structure of a crystal.
