Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

	Overview and Learning Objectives This activity introduces the fundamental principles of X-ray crystallography, and guides students through a series of activities for learning how structural information can be derived from X-ray diffraction patterns. Students will be able to: describe what can be detected with X-ray crystallography, proteins in particular; explain the impact of temperature, atom size, and impurities on the tests. return to top
