X-ray diffraction pattern of a crystal of alpha lactalbumen,a calcium-linked protein involved in the transport of calcium into the body. The white spots in the picture are concentrations of diffracted X-rays; the diffuse circular pattern is background "noise" from residual water in the crystal. In X-ray diffraction crystallography,complex computer programs are used to produce from a series of such images an electron density map of the crystal,which can then be used to determine the molecular structure | |
