In order to see these animations, the free program Chemscape Chime must be installed in your computer. Chime interaction with Internet Explorer is not seamless: an error message (which usually does not affect operation) often appears as links are followed. Should a structure not load correctly, it is enough to refresh the page, or to select it directly from the menu below.

A short summary of mouse commands in Chime.

Available animations:

  • Carbohydrates

    Secondary structure in proteins

  • α-helix
  • Parallel β-sheet
  • Anti-parallel β-sheet
  • Hemoglobin

  • Deoxyhemoglobin
  • Effects of O2 binding on heme and subunit geometries
  • Quaternary structure changes due to heme oxygenation
  • Electron transfer complexes in the respiratory chein

  • NADH dehydrogenase (complex I)
  • Succinate dehydrogenase (complex II)
  • Cytochrome bc1 (complex III)
  • Cytochrome c oxidase (complex IV)
  • A large number of animations is available through the Molecular Visualization Resources Index.

    The HTML code used in the animations was based on the templates provided by Eric Martz, in the University of Massachussets.
