Mundima yehunyanzvi hwekudya,vitamini Erakafanana ne "spearhead" yemaverick. Zvizhinjivitaminimaitiro anoita se coenzyme mukuita kwemakemikari, achitamba basa rekubatsira, uye vhitamini E yakasarudzika, ine simba rayo rakasimba kuchengetedza hutano hwevanhu. Vitamin E ndeyemafuta-solublevhitamini mhuri uye inotorwa benzodihydropyrane ine chimiro chakafanana uye biological chiitiko, kunyanya kusanganisira tocopherol uye tocotrienol. Boka rega rega rakakamurwa kuita ma subtypes mana, α, β, γ uye δ, maererano nemusiyano we methyl chinzvimbo pabenzopyrane mhete, huwandu hwe8 marudzi, uye idzi isomers dzine antioxidant kugona. Mahara radicals ikirasi yemamorekuru asina kugadzikana ane akanyanya kukwirira kemikari reactivity inogadzirwa mukuita kwemuviri metabolism. Ultraviolet mwenje, kusvibiswa kwezvakatipoteredza uye zvimwe zvinhu zvekunze zvinogona kukurudzira kugadzirwa kwemahara radicals, uye mitochondria inzvimbo zvakare yemahara radical kugadzirwa apo maseru anoita aerobic metabolism kupa simba. Yakawandisa yemahara radicals inokonzeresa oxidative kusagadzikana, iyo inorwisa biological macromolecules senge lipids, mapuroteni uye DNA mukati memasero, zvichikonzera kukuvara kweoxidative. Panguva dzakaoma, vhitamini E inotsamira pane yayo phenolic hydroxyl chimiro kuti ipe maatomu ehydrogen kuti aite nemahara radicals, kuderedza mahara radicals, kukanganisa oxidative chain reaction, uye nekudaro kudzivirira maseru.

Kunyungudika kwemafuta kwevhitamini E kunoita kuti igovaniswa munzvimbo dzakapfuma mune lipids, senge cell membranes uye lipoprotein. Panzvimbo idzi, inodzivirira zvakanyanya lipid peroxidation. Apo mahara radicals anorwisa polyunsaturated mafutaacids, ichikonzera lipid peroxidation chain reaction inokuvadza cell membranes uye lipoprotein, vhitamini E inogona kumisa maitiro panguva yekutanga uye kutapurirana matanho, kuchengetedza lipids muura, ropa, matishu uye sero membranes. Mu cardiovascular system,vitamini Einoderedza kugadzirwa kweoxidized yakaderera-density lipoprotein kuburikidza ne antioxidant effect, inoderedza kukuvadzwa kwayo kune vascular endothelial masero, uyezve inhibits kuumbwa uye kukura kweatherosclerotic plaque. Panguva imwecheteyo, vhitamini E inogona zvakare kudzora kuwanda uye kutama kwevascular smooth tsandanyama masero kuti arambe akajairwa uye kusimba kwetsinga dzeropa. Vitamin E inoitawo basa rakakosha mukudzivirira kwemuviri. Inokurudzira kupararira uye kusiyanisa kwemasero ekudzivirira muviri akadai seT uye B lymphocytes, inowedzera kuwirirana pakati pemasero, uye inowedzera maitiro ekudzivirira. Panguva imwecheteyo, inobatanidzwa mukugadzirisa kwehutachiona hwehutachiona hwehutachiona, hunokanganisa secretion uye kutaura kwe cytokines, uye inogadzirisa maitiro ekudzivirira. Masikirwo makuru evhitamini E anosanganisira mafuta emiriwo, nzungu, mhodzi, uye miriwo yemashizha egirinhi. Pakati pezvitubu izvi, mafuta emiriwo akapfuma muvhitamini E, kunyanya muchimiro che alpha-tocopherol. Mukuwedzera, pane multivitamin E zvinowedzera pamusika, kusanganisira softgel, chewable tablets uye creams, izvo zvakakodzera zvinodiwa nemapoka akasiyana evanhu. Zvichienderana nekudya kwekudya kwekudya kunongedzo, iyo inokurudzirwa kudya kwevhitamini E kune vanhu vakuru ndeye 15 mg pazuva (yakayerwa mune alpha-tocopherol yakaenzana). Nekudaro, data chaiyo yekuongorora inoratidza kuti avhareji yehuwandu hwevhitamini E inopedzwa nevakuru kuburikidza nekudya kwavo kwezuva nezuva kazhinji isingasviki 10 mg. Zvimwe zvidzidzo zvakaratidza kuti mune adjuvant therapy kune zvimwe zvirwere zvakadai sokunonoka kukwegura uye kuvandudza kukanganisa kwekuziva, kuwedzera 200-800 mg yevhitamini E zuva nezuva inogona kuva nemigumisiro. Kazhinji, vhitamini E yemuromo yakachengeteka, asi nguva yakareba yekudyara (kupfuura 1,000 mg pazuva) inogona kuwedzera mukana wekuita kwakaipa sengozi yekubuda ropa. Naizvozvo, kana uchishandisa vhitamini E yekuwedzera, zvakakosha kutevedzera kuraira kwenyanzvi kuve nechokwadi chekuchengetedza uye kurongeka kwekuwedzera.
