Because many studies have not distinguished between the S and R stereoisomers and, particularly in identifying tissue levels, the two EE isomers, 9-HODE is used here when the isomer studied is unclear.
Pošto mnoge studije nisu pravile razliku između S i R stereoizomera, niti na određivanje njihovih nivoa u tkivima, dva EE izomera, 9-HODE se koriste kad studirani izomer nije naveden.
