Hom phiaj: dej-soluble antioxidant
Kev Siv: siv los ua tshuaj reagent thiab chromatographic reagent
Siv: cov tshuaj vitamin, siv rau kev tiv thaiv thiab kev kho mob ntawm scurvy, kuj siv rau txhua yam mob thiab mob kis kab mob thiab purpura, thiab lwm yam
Siv: Vitamin C koom nrog hauv cov txheej txheem metabolic hauv lub cev, thiab tuaj yeem txhawb kev loj hlob thiab txhim khu kev tiv thaiv kab mob.Tuam Tshoj cov kev cai tuaj yeem siv los ntxiv dag zog rau cov khoom qab zib nyuaj nyuaj, kev siv 2000 ~ 6000mg / kg;Nyob rau hauv high hlau cereals thiab lawv cov kev npaj.Cov khoom (txhua hnub txwv tsis pub noj 50g) hauv kev siv 800 ~ 1000mg / kg;Qhov ntau npaum li cas hauv cov zaub mov muaj zog yog 300-500mg / kg;Hauv cov txiv hmab txiv ntoo khov khov, qhov ntau npaum li cas yog 200-400mg / kg;Qhov ntau npaum li cas hauv cov dej qab zib thiab cov mis nyuj haus yog 120 ~ 240mg / kg;Qhov ntau npaum li cas hauv cov txiv hmab txiv ntoo muaj zog yog 50 ~ 100mg / kg.Tsis tas li ntawd, cov khoom no muaj zog txo qis, tuaj yeem siv los ua antioxidant.
Kev siv: vitamin C koom nrog hauv cov txheej txheem metabolic hauv lub cev, tuaj yeem txhawb kev loj hlob thiab txhim khu kev tiv thaiv kab mob, tuaj yeem txhim kho qe tsim thiab qe zoo ntawm nqaij qaib.Thaum cov tsiaj tsis muaj vitamin C, yuav poob qab los noj mov, kev loj hlob stagnation, matt fur, anemia thiab lwm yam tsos mob.Tsis tas li ntawd, cov khoom no muaj lub zog txo qis, yog ib qho zoo antioxidant.
Siv: hluavtaws vitamin C yog tib yam li ntuj vitamin C. Cov khoom no tuaj yeem txhawb nqa folic acid rau tetrahydrofolic acid, yog qhov tsim nyog rau nucleic acid synthesis, txhawb kev tsim cov qe ntshav liab.Nws kuj tseem tuaj yeem txo cov ferric ions rau ferric ions, uas tau yooj yim nqus los ntawm tib neeg lub cev thiab muaj txiaj ntsig zoo rau tiam ntawm cov hlwb.Vitamin C koom nrog hauv kev tsim collagen hauv lub cev.Nrog neutralization toxin, txhawb kev tsim cov tshuaj tiv thaiv kab mob, tuaj yeem txhim kho lub cev detoxification muaj nuj nqi.Nyob rau hauv cov tshuaj, nws yog tsuas yog siv rau kev tiv thaiv los yog kev kho mob ntawm scurvy, raws li zoo raws li rau cov kab mob xws li caries, pos hniav abscess, anemia, kev loj hlob thiab kev loj hlob stagnation tshwm sim los ntawm tsis txaus los tiv thaiv cov ntshav acid.
Siv: tshuaj vitamin.Koom nrog hauv lub cev REDOX txheej txheem, txo cov capillary brittleness, ua kom lub cev tsis kam.Siv rau vitamin C deficiency, kub taub hau, mob nkim kab mob, thiab lwm yam
Siv: Siv reagent rau kev txiav txim siab ntawm arsenic, hlau, phosphorus thiab iodine, chromatographic tsom xam reagent, antioxidant, masking agent, txo tus neeg sawv cev.
