a A proposed biosynthetic pathway rationalizing the discovery of the never previously reported fatty acids FA 16:2n−3,10 (6,13-hexadecadienoic acid); FA 18:2n−3,10 (8,15-octadecadienoic acid) and FA 18:3n−3,10,13 (5,8,15-octadecatrienoic acid). The double bond configuration is tentatively assigned as cis in each case. b Associated extracted ion chromatograms and OzID MS/MS spectra of the 4-I-AMPP derivatized fatty acids. For the complete fatty acid profile, refer to the Supplementary Note 5, Supplementary Fig. 31 and Supplementary Data 3. Source data are provided as a Source Data file.
