13(R)-HODE

13(R)-HODE is the opposite enantiomer of the 13(S)-HODE produced when linoleic acid is incubated with soybean lipoxygenase. The presence of 13(R)-HODE in the supernatants and membranes of cultured bovine endothelial cells has been attributed to COX metabolism.¹ 13(R)-HODE is a weak (IC₅₀ = 2.7 μM) inhibitor of U-46619-induced platelet aggregation.²

ChEBI: 13(R)-HODE is a 13-HODE in which the stereocentre at position 13 has S-configuration. It is a conjugate acid of a 13(R)-HODE(1-).
