We chose to present several biochemical and pharmaceutical applications of molecular visualization.  Many biological functions depend on the actual shape of the compounds involved.  "Lock-and-key" processes are very common:  substrates fit neatly into enzymes, or stimulants into receptors.  Molecular visualization programs are a wonderful way to illustrate these relationships. 

If you can't see our molecules, or if you'd like to learn to make your own presentations, see our modeling and visualization resources page.
