An unknown dehydrogenase reduces 5(S)-hydroperoxy-18(R)-hydroxyeicosapentaenoic acid (5(S)-Hp-18(R)-HEPE) into the 18(R) stereoisomer of resolvin E2 (18(R)-RvE2). The unknown enzyme may be 5-hydroxyeicosanoid dehydrogenase (5-HEDH) or one similar to this (Patel et al. 2009). Human neutrophils biosynthesise RvE2 in greater amounts than RvE1, suggesting a significant role for RvE2 (Tjonahen et al. 2006, Oh et al. 2012).
