Iyo antioxidant mashandiro uye yemahara radical scavenging maitiro evhitamini E
Vitamin E ine antioxidant mhedzisiro, inoderedza uye inobvisa mahara radicals, uye inodzivirira muviri kubva mukukuvadzwa kweiyo oxidative kuburikidza nenzira dzinotevera:

1. Yakananga kuregeredza mahara radicals
Iyo molecular chimiro chevhitamini E, senge alpha tocopherol, inogona kusunga kune emahara radicals, senge reactive okisijeni marudzi (ROS), nekupa maatomu ehydrogen kuti asaparadze uye aashandure kuita zvinhu zvakagadzikana, nekudaro kumisa ketani kuita kwemahara radicals.
Iro lipophilic properties inobvumira kuti iite zvakasarudzwa mukati me lipid layer ye cell membrane, ichidzivirira zvakananga unsaturated mafuta acids mu membrane yesero kubva pakurwiswa kwemahara radical uye kuchengetedza kutendeseka kwesero membrane chimiro.
2. Kukanganisa lipid peroxidation cheni maitiro
Kana mahara radicals achirwisa cell membrane lipids, anokonzeresa kuita kweketani ye oxidation. Vitamin E inogona kukurumidza kubata lipid emahara radicals inogadzirwa panguva yelipid peroxidation, ichivharira kumwe kupararira kweiyo oxidative maitiro.
3. Bata pamwe nemamwe ma antioxidants kuti uwedzere mhedzisiro
Iyo synergistic mhedzisiro yemvura-soluble antioxidants senge vhitamini E uye vhitamini C: Vitamin E inobvisa lipid mahara radicals uye oxidize pachayo, nepo vhitamini C inogona kuibatsira kudzoreredza uye kudzoreredza chiitiko, ichigadzira antioxidant kutenderera.
Iyo chaiyo yekushandisa uye mhedzisiro yevhitamini E antioxidant
Kudzivirira ganda:
Deredza UV yakakonzera yemahara radical chizvarwa, kuderedza kukuvadzwa kwemafoto, uye kunonoka kuumbwa kwemakwinya uye pigmentation.
Inhibit tyrosinase chiitiko, kuderedza melanin synthesis, uye kupenya ganda tone.
Systemic antioxidant:
Deredza njodzi ye low-density lipoprotein (LDL) oxidation uye kudzivirira atherosclerosis.
Chengetedza nhengo dzakaita secrystalline lens uye maseru ekubereka anonzwa oxidation, uye kuderedza njodzi yezera-ane tarakiti uye kushaya mbereko.
