All of the files on the molecular models page (and some on this course page) contain chemical structure files in PDB (Protein Data Bank) format that are displayed in 3D by a plug-in developed by MDL Information Systems Inc. called Chemscape Chime. Compatible browsers and plug-in installation may be found at this link . These files may be saved locally and displayed outside of a browser with a program called RasMol. Many other files are presented in portable document format (.pdf extension) that require the Adobe Acrobat Reader plug-in to display. Click on the highlighted text in this paragraph for more information about the plug-ins.
