Usoro antioxidant na mmet?ta mkpochap? radical free nke vitamin E
Vitamin E na-ar? ?r? antioxidant, neutralizes na ikpochap? free radicals, ma na-echebe ah? si oxidative mmebi site na ?z? nd? a:

1. Kp?mkwem neutralize free radicals
?d?d? molek?la nke vitamin E, d? ka alfa tocopherol, nwere ike jik?ta na radicals n'efu, d? ka ?d? oxygen na-emeghachi omume (ROS), site n'inye hydrogen atom iji mee ka ha ghara ibibi ma mee ka ha gh?? ihe siri ike, si otú ah? na-akw?s? mmeghachi omume nke free radicals.
Njirimara lipophilic ya na-enye ya ohere itinye ?kachamma n'ime akwa lipid nke akp?kp? ah? cell, na-echebe ozugbo fatty acids na-enwegh? ab?ba na akp?kp? ah? cell site na mwakpo radical free na idobe iguzosi ike n'ezi ihe nke usoro akp?kp? ah? cell.
2. Kw?s? mmeghachi omume yinye peroxidation lipid
Mgbe free radicals wakpoo cell membrane lipids, ha na-akpalite a yinye mmeghachi omume nke oxidation. Vitamin E nwere ike weghara ngwa ngwa radicals efu na-emep?ta n'oge lipid peroxidation, na-egbochi mgbasawanye nke mmeghachi omume oxidative.
3. Na-emek?r?ta ihe na antioxidants nd? ?z? iji welie mmet?ta ah?
Mmet?ta synergistic nke antioxidants mmiri-soluble d? ka vitamin E na vitamin C: Vitamin E na-ekpochap? radicals free lipid na oxidizes onwe ya, ebe vitamin C nwere ike inyere ya aka ?maliteghachi na iweghachi ?r?, na-akp? okirikiri antioxidant.
Ngwa kp?mkwem na mmet?ta nke vitamin E antioxidant
Nchedo akp?kp?:
Belata ?gb? na-akpata radical na-akw?gh? ?gw? nke UV, belata mmebi fotoaging, ma na-egbu oge nhazi nke wrinkles na pigmenti.
Na-egbochi ?r? tyrosinase, belata njik? nke melanin, ma mee ka ?da akp?kp? ah? na-egbuke egbuke.
Usoro antioxidant:
Belata ihe ize nd? nke lipoprotein d? obere (LDL) oxidation ma gbochie atherosclerosis.
Chebe ak?k? ah? d? ka oghere kristal na mkp?r? nd? ?m?m? nke na-enwe mmet?ta maka oxidation, ma belata ihe ize nd? nke cataracts af? na enwegh? ?m?m?.
