Oxidation of 18:3n-3 by mycelia of Fot during short-time incubation in 0.1 M NaBO3 (pH 8.2). A: MS/MS analysis of products. Top: MS/MS analysis of HOTrE (m/z 293). Bottom: MS/MS analysis of KOTrE (m/z 291). The insets mark the elution of the identified products, 16- and 17-HOTrE, and 16-KOTrE, respectively. Small amounts of 12-OPDA (marked by arrow) eluted 3 min before 16-KOTrE. B: Chiral HPLC-MS/MS analysis (m/z 293 → full scan) of 16-HOTrE [m/z 235 (A−-58); top] and separation of 17-HOTrE [m/z 249 (A−-44); bottom].
