If you show arbitrary molecules loaded into the Protein Explorer, you can make a web page of links for your class which brings up these molecules.
When illustrating lectures, Don't forget to move your molecules early and often! You may be familiar with the 3D structure of the molecule you are showing, but it is all new to your students. Forgetting to move the structure often enough is a common pedagogic mistake -- it makes the molecule go "flat". The students can't see its 3D structure without rotation.
Each segment of your molecular visualization presentation should answer a question. The question and the answer should be explicitly stated.
A ready-to-assign exercise is offered by Charles Sackerson, Iona College, New Rochelle NY. A sequence is given, with instructions for finding the molecule with BLAST. Next, using BLASTX, the six possible translated amino acid sequences are obtained and matching proteins are listed. Disease associations are noted. The molecule is then searched for at the PDB, and the 3D structure viewed in Chime.
