The Chem3D app is an excellent (and free!) app to view the three-dimensional structures of proteins and macromolecules. The app handles conventional iPad finger navigation mechanics very well, with fast response times. App users can begin by selecting one of the sample structures included in the app, or they can search the entire Protein Data Bank from within the app to download other sample files. The settings menu allows users to toggle among four different display modes: wire frame, ball and stick, space-filling, and cartoon. Additionally, users can choose to enable “rocking mode,” which adds motion to the model. The background color can also be adjusted. Screen images can be emailed, shared via social media, or saved to the camera roll.
