Licorice or stick: show all the bonds between atoms.

Ribbons: depicts structural motifs (helices and sheets),.

There are 4 different representations that are commonly used: When trying to visualize molecules, it is important to keep in mind there is no "right" image for them, we can represent atoms in a variety of manners that best present the features we want to convey. I’m using Chimera here, but the workflows is virtually the same if you use something else like PyMol or VMD. Once you have your PDB file, you can render it on a molecular visualizer.

If what you want is some small molecule, you can try searching for the structure online, or can draw it using Avogadro, a free and open source molecule editor you can get at Visualizing and Exporting Models If you can't find your molecule, if it's not on the PDB it's probably because nobody knows it's structure yet. If you’re looking for cool structures and some explanations, the molecule of the month PDB articles at are a good way to start browsing. The biggest such database is the Protein Data Bank at

These structures are determined using an array of techniques such as x-ray crystallography and nuclear magnetic resonance, and when they are published they are also deposited in databases and become freely available for download.

The files containing the atoms coordinates for a molecule are called.

9 Mixing Different Representations to Obtain Great Modelsįirst, you need the coordinate file of the molecule you want to print.
