Fatty Acids

Structure images and info for more than 400 fatty acids. Click links to find species that produce a fatty acid, publications, and data.
Click 'Tree' to display phylogenetic distribution of plants that produce a fatty acid.

1 Structures drawn at OPSIN (opsin.ch.cam.uk)
2 Note: Many publications report FA contents as 18:1, 18:2, 18:3, etc. without specifying double bond position or configuration whereas other analyses specify oleic (18:1 delta 9c), linoleic acid, etc. SOFA (and PlantFAdb) store these data separately.
