Vitamin E yog ib pawg ntawm cov rog soluble tebchaw uas suav nrog plaub tocopherols thiab plaub tocotrienols.Nws yog ib qho tseem ceeb tshaj plaws antioxidants. Nws yog Fat-soluble organic solvents xws li ethanol, thiab insoluble nyob rau hauv dej, tshav kub, acid ruaj khov, base-labile. Vitamin E tsis tuaj yeem tsim los ntawm lub cev nws tus kheej tab sis yuav tsum tau txais los ntawm kev noj haus lossis tshuaj ntxiv. Plaub yam tseem ceeb ntawm ntuj vitamin E, suav nrog ib txwm tshwm sim d-alpha, d-beta, d-gamma thiab d-delta tocopherols. Piv nrog rau daim ntawv hluavtaws (dl-alpha-tocopherol), lub ntuj daim ntawv ntawm vitamin E, d-alpha-tocopherol, zoo dua khaws cia los ntawm lub cev. Lub bio muaj (muaj rau siv los ntawm lub cev) yog 2: 1 rau natural-source Vitamin E tshaj hluavtaws vitamin E.
