Isixhobo sokulwa ne-antioxidant kunye nesiphumo sasimahla sokutshabalalisa ivithamin E
I-Vitamin E yenza iziphumo ze-antioxidant, i-neutralize kwaye icoca ii-radicals zamahhala, kwaye ikhusela umzimba kumonakalo owenziwe nge-oxidative ngeendlela ezilandelayo:

1. Ukunciphisa ngokuthe ngqo ii-radicals zamahhala
Ubume bemolekyuli yevithamin E, efana nealpha tocopherol, inokubophelela kwiiradicals zasimahla, ezinje ngeentlobo zeoksijini esebenzayo (ROS), ngokubonelela iiathom zehydrogen ukuba zizenze zingonakalisi kwaye ziziguqule zibe zizinto ezizinzileyo, ngaloo ndlela ziphelise ukusabela kwetsheyini yeeradicals zasimahla.
Iimpawu zayo ze-lipophilic zivumela ukuba zifakwe ngokufanelekileyo kwi-lipid layer ye-membrane yeseli, ikhusela ngokuthe ngqo i-unsaturated fatty acids kwi-membrane yeseli ekuhlaselweni kwe-radical free kunye nokugcina ingqibelelo yesakhiwo se-membrane yeseli.
2. Ukuphazamisa i-lipid peroxidation chain reaction
Xa i-radicals yamahhala ihlasela i-lipids yeseli yeseli, ibangela ukusabela kwekhonkco ye-oxidation. IVithamin E inokubamba ngokukhawuleza iiradicals zasimahla zelipid ezenziwe ngexesha le-lipid peroxidation, ithintele ukusasazwa ngakumbi kokusabela kwe-oxidative.
3. Ukusebenzisana namanye ama-antioxidants ukuphucula umphumo
Impembelelo ye-synergistic ye-antioxidants e-soluble yamanzi efana ne-vitamin E kunye ne-vitamin C: I-Vitamin E icoca i-lipid free radicals kunye ne-oxidizes ngokwayo, ngelixa i-vitamin C inokukunceda ukuhlaziya nokubuyisela umsebenzi, ukwenza umjikelezo we-antioxidant.
Isicelo esithile kunye nesiphumo se-vitamin E antioxidant
Ukhuseleko lolusu:
Ukunciphisa i-UV ebangela i-radical simahla isizukulwana, nciphisa umonakalo wokufota, kwaye ulibazise ukwakheka kwemibimbi kunye ne-pigmentation.
Ukuthintela umsebenzi we-tyrosinase, ukunciphisa i-melanin synthesis, kwaye ukhanyise ithoni yesikhumba.
I-antioxidant yenkqubo:
Ukunciphisa umngcipheko we-low-density lipoprotein (LDL) oxidation kunye nokukhusela i-atherosclerosis.
Khusela amalungu anje nge-crystalline lens kunye neeseli zokuzala ezibuthathaka kwi-oxidation, kwaye unciphise umngcipheko we-cataracts ezinxulumene nobudala kunye nokungazali.
