Molecules offers an incredible three-dimensional view of molecules. Users have the control to alter the view of the molecules by rotating them, zooming in on them, and more all through the use of their fingers.
This free app also allows users to get a hands-on view of how molecules are composed and they can create their own specific molecules. This application is a great guide for visual learners and is free.
From its website: Molecules is an application for the iPhone, iPod touch, and now iPad that allows you to view three-dimensional renderings of molecules and manipulate them using your fingers. You can rotate the molecules by moving your finger across the display, zoom in or out by using two-finger pinch gestures, or pan the molecule by moving two fingers across the screen at once. The combination of the iPhone, iPod touch, and iPad's unique multitouch input system and the built-in OpenGL ES 3-D graphics capabilities enable you to feel like you are manipulating the molecules themselves with your fingers.
New molecules can be downloaded from the RCSB Protein Data Bank (http://www.rcsb.org/pdb), an international repository of biological molecules and their 3-D structures, or NCBI's PubChem, a public database of compounds. Molecules can be downloaded directly to your handheld device and stored there for later viewing. In addition, you can view detailed information about the molecule, such as the researchers who established its structure, its amino acid or nucleotide sequence, and its full name. Multiple visualization modes can be switched to by double-tapping on the 3-D rendering.
Custom molecule structures can also be downloaded to the device from any publicly available web server. The location of these structures can either be manually specified in the application, or custom URLs can be clicked on within Safari or Mail on the device. This will launch Molecules and have it start downloading the file at that address.
On iPad, molecular structures can now be dragged into the application directly using iTunes by going to the Applications tab, scrolling down to the bottom, and clicking on the Molecules icon.
