John Shanklin and Ed Whittle (IMAGE) DOE/Brookhaven National Laboratory Caption Brookhaven Lab biochemist John Shanklin with retired biology associate Ed Whittle displaying a structural image of a desaturase enzyme that introduces adjacent hydroxyl groups into a fatty acid. This fatty acid can be used to synthesize a wide range of organic molecules, so the discovery of the plant enzyme may inspire the development of new "greener" industrial catalysts.
