How to read the 3D model

Atoms use the standard CPK colors: carbon gray, hydrogen white, oxygen red, nitrogen blue, sulfur yellow. Switch to Spacefill to see the molecule's overall shape and size, or Stick for a clear view of the bonds. Click two atoms in distance mode to measure a bond length in ångströms.

3D coordinates are PubChem's computed conformer, one low-energy shape of the molecule. Flexible molecules can take many other shapes.
