Structures - Molecular Viewer

Structures is a powerful, easy-to-use tool for displaying and analyzing the 3D structures of molecules, large and small. Structures is designed specifically for the Mac, with full support for Dark Mode, iCloud, Auto Save, gestures, drag and drop, configurable preferences, customizable toolbar, full-screen mode, unlimited undo/redo and more. With Structures, you can: • Load atomic coordinates from files or directly from the Protein Data Bank. Structures reads the most common macromolecular and small-molecule file formats. • Display atoms in sphere, stick, and ball-and-stick representations. Show ribbon, tube, or chain-trace representations of macromolecules, along with solvent-accessible or solvent-excluded surfaces. • Choose from a variety of automatic color schemes. • Select atoms onscreen using the trackpad/mouse, or type in an atom description using a simple atom matching syntax. • Measure distances and angles between atoms. • Save specific views of a molecule and animate transitions between them. • Create and record complex animations for presentations and videos. • Print or save static images. And new features arrive regularly.
