The four 9-HODE isomers, particularly under conditions of oxidative stress, may form together in cells and tissues; they have overlapping but not identical biological activities and significances.
Četiri 9-HODE izomera, posebno pod uslovima oksidativnog stresa, mogu se zajedno formirati u ćelijama i tkivima; oni imaju preklapajuće mada ne i identične biološke aktivnosti i značaje.
