Arachidonic acid 3D structure

Arachidonic acid (also called cis-5,8,11,14-Eicosatetraenoic acid, 5Z,8Z,11Z,14Z-eicosatetraenoic acid) has the formula C₂₀H₃₂O₂ and a molar mass of 304.5 g/mol. The model above is PubChem's computed 3D conformer: drag to rotate, scroll to zoom, and use the measurement tools to read bond lengths and angles.

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.
