On a recent visit to a major US university, I had occasion to stop outside the towering steel gates leading into the main courtyard of the newly-constructed chemistry building. I glanced up, and saw organic molecules, decked out in bronze, blue, and red.
On either side of the gate are polypeptides, four residues each, that use standard amino acid abbreviations to spell out a four-letter word* on either side. Pictured (at left) is the left-hand gate.
Here are artistic molecules done right - correct bond angles, color-coded atoms, even double bonds! They're certainly better rendered than most of the recent ChemBark "WWWTP?" posts.
*(Need a hint? Only so many schools have four-letter names!)
