[Hemoglobin oxidation and erythrocyte hemolysis induced by a synthetic analog of alpha-tocopherol not containing an isoprenoid chain].

The effect of alpha-tocopherol and its synthetic analogue which does not contain an isoprenoid chain, 2,2,5,7,8-pentamethyl-6-hydroxychroman (chromanol), on rat erythrocyte and hemoglobin has been studied. Chromanol, unlike alpha-tocopherol, induces oxidation of hemoglobin into aquomethemoglobin and causes erythrocyte hemolysis. A mechanism of the reaction has been established.
