I-antioxidant ye-antioxidant kanye nomphumela wamahhala wokukhipha i-vitamin E
I-Vitamin E inemiphumela ye-antioxidant, yenza i-neutralize futhi isuse ama-radicals mahhala, futhi ivikela umzimba emonakalweni we-oxidative ngezindlela ezilandelayo:

1. Ngqo nciphisa ama-radicals mahhala
Isakhiwo samangqamuzana kavithamini E, njenge-alpha tocopherol, ingabophezela kuma-radicals mahhala, njengezinhlobo ze-oxygen esebenzayo (ROS), ngokuhlinzeka ngama-athomu e-hydrogen ukuze awenze angonakalisi futhi awaguqule abe izinto ezinzile, ngaleyo ndlela anqamule ukusabela kweketango lama-radicals mahhala.
Izakhiwo zayo ze-lipophilic zivumela ukuthi ishumeke ngokukhethekile kungqimba lwe-lipid ye-membrane yeseli, ivikela ngokuqondile ama-acids angenayo i-unsaturated ku-membrane yeseli ekuhlaselweni kwama-radical mahhala futhi igcine ubuqotho besakhiwo se-membrane yeseli.
2. Phakamisa ukusabela kweketango le-lipid peroxidation
Lapho ama-radicals wamahhala ehlasela ulwelwesi lwama-lipids weseli, aqala ukusabela kochungechunge lwe-oxidation. I-Vitamin E ingabamba ngokushesha ama-radicals mahhala e-lipid akhiqizwa ngesikhathi se-lipid peroxidation, ivimbele ukusakazeka okuqhubekayo kokusabela kwe-oxidative.
3. Sebenzisana namanye ama-antioxidants ukuze uthuthukise umphumela
Umphumela we-synergistic we-antioxidant encibilikayo emanzini njenge-vitamin E ne-vitamin C: I-Vitamin E isusa ama-radicals mahhala e-lipid futhi i-oxidize ngokwayo, kuyilapho i-vitamin C ingayisiza ukuthi ivuselele futhi ibuyisele umsebenzi, yenza umjikelezo we-antioxidant.
Ukusetshenziswa okuqondile kanye nomphumela we-vitamin E antioxidant
Ukuvikelwa kwesikhumba:
Yehlisa isizukulwane samahhala se-UV esibangelwa ama-radical, wehlise umonakalo wokuthwebula izithombe, futhi ubambezele ukwakheka kwemibimbi nokuba nemibala.
Vimbela umsebenzi we-tyrosinase, wehlise ukwakheka kwe-melanin, futhi ukhanyise ithoni yesikhumba.
I-antioxidant yesistimu:
Yehlisa ubungozi be-low-density lipoprotein (LDL) oxidation futhi uvimbele i-atherosclerosis.
Vikela izitho ezifana ne-crystalline lens namaseli okuzala azwelayo ku-oxidation, futhi wehlise ubungozi bolwelwesi oluhlobene nobudala nokungazali.
