Reaction: ALOX5 oxidises 18(R)-HEPE to 5(S)-Hp-18(R)-HEPE

- in pathway: Biosynthesis of E-series 18(R)-resolvins
Unlike resolvin E3, which is biosynthesised in eosinophils or resident macrophages via the 15-lipoxygenase (ALOX15) pathway, resolvins E1 and E2 are biosynthesised by neutrophils via the 5-lipoxygenase pathway. In neutrophils, ALOX5 oxidises 18(R)-hydroxyeicosapentaenoic acid (18(R)-HEPE) to 5(R)-hydroperoxy-18(R)-hydroxyeicosapentaenoic acid (5(R)-Hp-18(R)-HEPE) (Tjonahen et al. 2006, Oh et al. 2012).
