Chimiro chemakemikari chine benzopyrane mhete uye hydrophobic parutivi cheni, izvo zvinopa iyo lipid membrane kupinda 67.
zvemuviri uye zvemakemikari zvimiro

Solubility : inonyungudika mumafuta, ethanol uye zvimwe organic solvents, isinganyunguriki mumvura 12.
Kugadzikana : inodzivirira kupisa (≤200 ° C) uye nharaunda dzine acidic asi inonzwa kune alkali, okisijeni, UV mwaranzi uye maion esimbi (Fe3 + + / Cu2 +). Frying inoparadza zvakanyanya chiitiko

Chekutanga, antioxidant synergistic mechanism yemahara radical scavenging circulatory system

Vitamin E, semafuta-soluble antioxidant, inosarudza kusabvisa lipid isina radicals mumasero membranes, nepo vhitamini C, semvura inonyungudika antioxidant, inoderedza uye inovandudza oxidized vitamin E (tocopherol free radicals), ichigadzira inoenderera antioxidant cycle 17.
Ongororo dzinoratidza kuti kusanganiswa kwezviviri izvi kunogona kuvandudza antioxidant kunyatsoshanda ne3 nguva, imwe molecule vitamin E inogona kuramba ichibvisa kusvika ku4 mahara radicals, vhitamini C kuburikidza nenzira yekuzvarwa patsva kuti iwedzere nguva yayo yekuita 78.

Interphase Defense network

Vitamin E inomisa iyo lipid bilayer yesero membrane uye inovharira iyo lipid peroxidation chain reaction. Vitamin C inochera mvura-inonyungudika yemahara radicals mucytoplasmic matrix kugadzira lipid - mvura biphasic kudzivirira system 13.

Chechipiri, immune system bidirectional activation effect inosimudzira innate immune immune ?: Vitamin C inosimudzira neutrophil chemotaxis, vhitamini E inosimudzira NK cell chiitiko, uye musanganiswa unoderedza chiitiko chekufema turakiti utachiona ne32% 15.
inogadzirisa hutachiona hwehutachiona: synergistically inomutsa T lymphocyte kuwanda, inovandudza kugadzirwa kwemasoja ekudzivirira chirwere ne28%, uye ine mhedzisiro inobatsira pamhinduro yejekiseni 57.

Chechitatu, ganda utano pamwe kupindira nzira

Kudzivirirwa kwemifananidzo

Vitamin E inhibit UV-induced sepiperoxidation uye vhitamini C inovhara tyrosinase chiitiko, yakakosha enzyme mu melanin synthesis, uye musanganiswa unoderedza mwero weganda erythematosis ne54% 24.

Kudzora kwe collagen metabolism

Vitamin C inomisa prolyl hydroxylase kukurudzira collagen synthesis, uye vhitamini E inoderedza collagenase chiitiko kudzivirira kudzikira. Miedzo yemakiriniki yakaratidza kuti elasticity yeganda inovandudzwa ne23% uye kudzika kwemakwinya kunoderedzwa ne19% 34.

4. Kubatana kwemaitiro ekudzivirira kwemoyo
atherosclerosis kupindira : Vitamin E inhibits oxidation yeyakaderera-density lipoprotein (LDL) uye vhitamini C inogadzirisa yakakuvadzwa vascular endothelium pamwe chete ne18% yakaderera njodzi yemoyo vascular zviitiko 15.
microcirculation kunatsiridza : vhitamini E inoderedza kusarongeka kweplatelet aggregation, vhitamini C inosimudzira capillary kuoma, uye ine kukosha kwekudzivirira kwemajoini uye kurapwa kwechirwere cheshuga retinopathy 58.

5. Metabolic cooperative optimization maitiro
iron metabolism regulation : Vitamin C inoderedza iyo trivalent iron kune bivalent iron, inovandudza chiyero chekunyura 2-3 nguva; Vitamin E inodzivirira erythrocyte membrane kugadzikana uye inoderedza njodzi yehemolysis 57.
cholesterol chiyero: Vitamin E inhibits HMG-CoA reductase kuderedza cholesterol synthesis, vhitamini C inosimudzira bile acid kubuda, uye pamwe chete inoderedza yakazara cholesterol mazinga ne12% -15%
