Intshayelelo yeMveliso
IVitamin E (VE) ligama eliqhelekileyo leetocopherols, ekwaziwa ngokuba yiVitamin E, eyinto enamafutha egolide okanye emthubi enevumba elikhethekileyo. Ngokwesiqhelo iVitamin E ixutywa lula ngumoya ekukhanyeni kwaye ibonakala ibomvu obumnyama. Ixutywa ne-acetone, i-chloroform, i-ether, okanye ioyile yemifuno, kwaye ayinyibiliki emanzini. IVitamin E yenye yeevithamini zokuqala ezafunyanwa, ezafunyanwa okokuqala nguEvans noBishop kwiYunivesithi yaseCalifornia. Emva koko ngo-1924, iYunivesithi yaseArkansas Sure yabiza le nto ngokuthi yiVitamin E. Yivithamini ebalulekileyo enyibilikayo ngamafutha, njenge-antioxidant kunye nesondlo esihle, isetyenziswa kakhulu kwiklinikhi, amayeza, ukutya, ukutya, iimveliso zempilo kunye nezimonyo kunye neminye imboni.

Umsebenzi weMveliso
I-Vitamin E inemisebenzi kunye neziphumo ezifana ne-antioxidant, ukuthintela umhlaza, kunye nokuphucula ukuxhathisa.
1. I-Antioxidant. I-Vitamin E yi-vitamin enyibilikayo emafutheni enokuxhathisa ngempumelelo i-oxidation, ilibazise ukwaluphala komntu, kwaye inciphise imibimbi. Ukongeza, inokunciphisa ukusetyenziswa kweoksijini kwiiseli, yonyuse ukunyamezela komntu, kwaye inciphise iimpawu ezifana nokuba ndindisholo emilenzeni nasezinyaweni, ukuqaqamba ezandleni nasezinyaweni. Ukongeza ekubeni yi-antioxidant, inokukhusela iiseli zomzimba ekonakaleni kwe-free radicals.
2. Ukuthintela umhlaza kunye nokonyusa ukumelana nezifo. I-Vitamin E inokuthintela ukwenzeka komhlaza kwaye ithintele ukukhula kweethumba ukuya kwinqanaba elithile. I-Vitamin E ikwadlala indima ethile ekonyuseni ukumelana nezifo. Inokuphucula amandla omzimba okuzikhusela kwaye ikhuthaze ukuveliswa kwee-antibodies zentsholongwane emzimbeni, ngaloo ndlela iphucula amandla omzimba okulwa nentsholongwane.
Isicelo seMveliso
(1) Abantu abasela amanzi empompini ane-chlorine kufuneka bathathe i-vitamin E engakumbi;
(2) Abantu abasebenzisa izithintelo zokukhulelwa, i-aspirin, utywala, iihomoni kufuneka bongeze i-vitamin E;
(3) isifo sentliziyo, izigulane zesifo sikaParkinson, abafazi abakhulelweyo kunye nabantu abakwiminyaka ephakathi kunye nabantu abadala ukongeza kwi-vitamin E;
(4) Inkqubo yemithambo-luvo ekhulayo yabantwana inobuthathaka kakhulu kukungabikho kwevithamini E, kwaye xa ukunqongophala kwevithamini E kunganyangwa nge-vitamin E ngexesha elifanelekileyo, iimpawu zemithambo-luvo zinokuvela ngokukhawuleza.
(5) I-Vitamin E ibaluleke kakhulu ekuphuhlisweni nasekukhuleni kweemveku ezingekazalwa neentsana, kwaye inokuphucula umgangatho wesondlo kubafazi abakhulelweyo nabancancisayo.
(6) Ukongezwa kwevithamini E kwizigulane ezine-hypertension okanye izifo zentliziyo kunye nemithambo yegazi kunokunceda ukunciphisa uxinzelelo lwegazi, ukunciphisa umonakalo we-oxidative kwi-vascular intima, kunye nokuthintela ukwenzeka kwezifo zentliziyo kunye nemithambo yegazi.
(7) I-Vitamin E inokuphucula ukusebenza kwenkqubo yokuzikhusela komzimba kwaye iphucule ukumelana komzimba, ngelixa i-vitamin E inokukhusela ulusu ekonakaleni yi-UV, inciphisa umngcipheko wokutshiswa lilanga kunye nokwaluphala kwesikhumba.
