Ivithamini E
Intshayelelo
IVitamin E, ekwaziwa ngokuba yi-tocopherol, sisithako esilwa ne-antioxidant kunye nesondlo esisebenza kakuhle kakhulu. Kwangaxeshanye, ineempawu zomsebenzi ophezulu webhayoloji kunye nokutya okukhuselekileyo. Isetyenziswa kakhulu kumayeza, kwiimveliso zokhathalelo lwempilo, ekutyeni, kwizithambiso nakwezinye iindawo.
Iipropati ze-physicochemical
IVitamin E lulwelo olucacileyo olutyheli kancinci ukuya kolutyheli okanye olutyheli-luhlaza olucacileyo, oluphantse lube nevumba elibi, kwaye umbala uba mnyama kancinci xa luvezwa ekukhanyeni. Uhlobo lwendalo luya kunyangeka kwaye lunyibilike malunga nama-25℃. Yivithamini enyibilikayo ngamafutha eneentlobo ezisi-8 zendalo. I-Chemicalbook yahlulwe yaba ziintlobo ezi-4 ze-tocopherols kunye neentlobo ezi-4 ze-triene tocopherols. Oko sikubiza ngokuba yi-vitamin E kubhekisa kwi-α-tocopherol, olulwelo olutyheli-luhlaza olucacileyo noluqinileyo, olunyibilikayo lula kwizinyibilikisi ze-organic, olunganyibilikiyo emanzini, oluzinzileyo kubushushu, olungagungqiyo kakhulu kwi-oxygen, kwaye kulula kakhulu ukulufaka kwi-oxidize.
Imisebenzi yefiziyoloji
IVitamin E sisondlo esisisiseko esingaziwa kakuhle umsebenzi waso. Siyi-antioxidant. Ingadityaniswa neselenium ekutyeni ukuthintela ii-polyunsaturated fatty acids kwiimembrane nakwezinye izakhiwo zeeseli ekonakaleni kwe-free radicals; ukukhusela iiseli ezibomvu zegazi kwi-haemolysis, kunye nokukhusela imithambo-luvo kunye nemisipha ekonakaleni kwe-Chemicalbo Ok oxygen free radicals, ukugcina uphuhliso oluqhelekileyo kunye nomsebenzi wemithambo-luvo kunye nemisipha. Isenokuba yinto encedisayo kwezinye iinkqubo ze-enzyme. Le mveliso ithatha inxaxheba kwezinye iimpendulo ze-metabolic emzimbeni, ezinokulwa ne-peroxidation ye-free radicals, ukulwa nokwaluphala, ukukhusela ulusu, ukuphucula umsebenzi we-ovarian, kunye nokuthintela ukukhupha isisu rhoqo.
