ʻO ka Alpha-tocopherol synthetic (Tocopherol, Alpha-tocopherol synthetic, vitamin E, E307) he antioxidant e pale ana i nā pūnaewele mai ka pōʻino ma o ka hoʻolohi ʻana i ka oxidation o nā lipids (momona) a me ka hoʻokumu ʻana o nā radical manuahi.
ʻIke ʻia ʻo Alpha-tocopherol ma ke ʻano he antioxidant biology nui loa i loko o ke kino o ke kanaka. ʻO ke ana ʻana o ka hana vitamini E i nā hui honua (IU) i hoʻokumu ʻia i ka hoʻonui ʻana o ka momona ma muli o ka pale ʻana i nā hānau ʻole kūpikipiki i nāʻiole hāpai i ka lawe ʻana i ka alpha-tocopherol. Hoʻonui kūlohelohe ia ma kahi o 150% o ka maʻamau i ke kino o ka makuahine i ka wā hāpai i nā wahine.
1 IU o ka wikamina E ua wehewehe ʻia e like me ke olaola o 0.667 milligrams o RRR-alpha-tocopherol (i kapa ʻia ʻo d-alpha-tocopherol a i ʻole 1 milligram o ka all-rac-alpha-tocopheryl acetate (ʻoihana i kapa ʻia ʻo dl-alpha-tocopheryl acetate, ʻo ke kumu kumu d, l-synthetic moleki compound, kūpono inoa ʻia ʻo 2-ambo-alpha-tocopherol, ʻaʻole hana hou ʻia).
