In an alternative route to the production of protectins PD1n-3DPA and PD2n-3DPA, 17(S)-hydroperoxy-docosapentaenoic acid (17(S)-Hp-DPAn-3) can be further oxygenated by a lipoxygenase to form 7,17-dihydroperoxy-docosapentaenoic acid (7,17-diHp-DPAn-3) (Dalli et al. 2013). Although this is a proposed biosynthetic route, it is assumed DPAn-3-derived SPMs follow a similar synthesis route to DHA- and EPA-derived SPMs therefore the lipoxygenase could be the dual-functional 5-lipoxygenase (ALOX5).
