Electron impact–MS of fatty acids accumulated in 155NS1. A mixture of peaks 2 and 3 from Fig. 3 was analyzed. Fragmentation shown in the Inset (from ref. 19) generates the ions with m/z of 514 and 542 (see text), CO2, and p-bromophenacylalcohol, the last compound fragmented further to produce the most prominent doublet at m/z 183/185, as also was seen in ref. 19.
