Effect of dietary vitamin E on the production of platelet 12-hydroxyeicosatetraenoic acid (12-HETE).
Collagen and thrombin challenged platelets from vitamin E-deficient rabbits generated significantly more 12-HETE when compared to the platelets from vitamin E-supplemented rabbits. Similarly, conversion of arachidonic acid to 12-HETE was increased in platelets from vitamin E-deficient rabbits. These data show that vitamin E plays a role not only in deacylation of platelet phospholipids but also in the lipoxygenase mediated reactions.
