Biological Context

(±)12-HETE is a racemic mixture of the arachidonic acid metabolites 12(R)-HETE and 12(S)-HETE . It is formed via non-enzymatic oxidation of arachidonic acid .^1,2 12(S)- and 12(R)-HETE are formed by 12S- and 12R-lipoxygenase-mediated oxidation of arachidonic acid, respectively.^3,4,5 12(R)-HETE can also be formed by oxidation of arachidonic acid mediated by cytochrome P450 (CYP450) enzymes.¹ (±)12-HETE (1 µM) induces aggregation of isolated human neutrophils.⁶ Production of (±)12-HETE by platelets isolated from spontaneously hypertensive rats is increased compared with platelets isolated from normotensive rats.⁷
