Antioxidant mechanism komanso mphamvu yowononga yaulere ya vitamini E
Vitamini E imakhala ndi antioxidant zotsatira, imachepetsa ndikuchotsa ma radicals aulere, ndipo imateteza thupi ku kuwonongeka kwa okosijeni kudzera m'njira izi:

1. Mwachindunji muchepetse ma free radicals
Mapangidwe a mamolekyulu a vitamini E, monga alpha tocopherol, amatha kumangiriza ma radicals aulere, monga mitundu ya okosijeni yokhazikika (ROS), popereka maatomu a haidrojeni kuti asawononge ndikusandutsa zinthu zokhazikika, potero amathetsa ma chain reaction of free radicals.
Mapangidwe ake a lipophilic amawalola kuti alowetsedwe mu lipid wosanjikiza wa cell membrane, kuteteza mwachindunji unsaturated mafuta zidulo mu cell nembanemba ku ma free radicals kuukira ndi kusunga kukhulupirika kwa nembanemba dongosolo.
2. Kusokoneza mayendedwe a lipid peroxidation
Ma radicals aulere akamawononga lipids mu cell membrane, amayambitsa kusakanikirana kwa okosijeni. Vitamini E amatha kugwira mwachangu ma lipid free radicals opangidwa panthawi ya lipid peroxidation, kutsekereza kufalikira kwa okosijeni.
3. Gwirizanani ndi ma antioxidants ena kuti muwonjezere zotsatira
Mphamvu ya synergistic ya ma antioxidants osungunuka m'madzi monga vitamini E ndi vitamini C: Vitamini E imachotsa ma radicals aulere komanso oxidize yokha, pomwe vitamini C imatha kuthandizira kukonzanso ndikubwezeretsa ntchito, ndikupanga kuzungulira kwa antioxidant.
Ntchito yeniyeni ndi zotsatira za vitamini E antioxidant
Chitetezo pakhungu:
Chepetsani m'badwo waulere wa UV, chepetsa kuwonongeka kwa mafoto, ndikuchedwetsa kupanga makwinya ndi mtundu.
Kuletsa ntchito ya tyrosinase, kuchepetsa kaphatikizidwe ka melanin, ndikuwunikira khungu.
Systemic antioxidant:
Kuchepetsa chiopsezo cha oxidation ya low-density lipoprotein (LDL) ndikupewa atherosulinosis.
Tetezani ziwalo monga magalasi a crystalline ndi ma cell obala omwe amakhudzidwa ndi okosijeni, komanso kuchepetsa chiopsezo cha ng'ala ndi kusabereka.
