Explore the fascinating world of biological macromolecules:
iMolview lets you browse and view in 3D protein and DNA structures from Protein Data Bank, drug molecules from DrugBank, and small molecules from Pubchem. Search for drug names like 'ibuprofen' or 'gefitinib' in DrugBank, or proteins like 'insulin' or 'thyroid receptor' in PDB. Information associated with each molecule in these databases is also at your fingertips. Sync and view your own structure files via iTunes. Molecular view can be customized with a rich set of molecular representations (wires, balls-and-sticks, space filling, ribbon diagrams, molecular surfaces) and various coloring schemes. Select residues, atoms or chains and color or change their representations individually. Select 'neighbors' of a ligand or any other selection to identify interacting atoms or residues. Set 'inertia' to the maximum and let your molecule spin in 3D indefinitely.
Save the current scene (viewpoint + representation) as a slide which can be easily accessed later. Save the whole molecular document with multiple slides.

Huge Bonus


Oh wow, they just added search for PubChem that suddenly let's me view small molecules, and with surface turned on with the electrostatic (or binding properties) view option, I can *see* an estimate of the real character of drug molecules. This is certainly the best visualizer out there for the iPhone. It's so far too slow to make surfaces for large proteins though, on an iPhone 5. Still, it quickly helps me better understand each week's biochemistry headlines since most reported studies already have sent their structural results to the Protein Data Bank.

Great AP


Beautiful graphics. Easy to use. The preprocessed displays allow quick and easy visualization of the key aspects of the crystal structures. It has a nice range of functionality for a 99 cent AP. Terrific for education but some real work can also be done with it.

Useful app


I have spent the last 2 hours exploring my favorite structures with this app. Great fun and being able to touch and interact with them is very cool - needs a few more features such as save image
