FIG 2.
GC-MS analysis of products formed by incubation of oleic acid with control (Co) and CYP52M1 (M1) microsome protein (in vitro system). (A) Chromatogram for ion trace m/z 337. The mass spectra of peaks 1 and 2 yield fragmentation patterns identical to those of 17-hydroxy oleic acid (B) (21) and 18-hydroxy oleic acid (C) (22).
