Ascorbic Acid tseem hu ua vitamin C
Taw qhia
Ascorbic Acid yog polyhydroxy compound nrog cov tshuaj formula C6H8O6. Cov qauv zoo ib yam li cov piam thaj, thiab ob pawg enol hydroxyl nyob ib sab ntawm 2nd thiab 3rd txoj haujlwm hauv cov molecule tau yooj yim dissociated kom tso H +, yog li nws muaj qhov xwm ntawm cov kua qaub, tseem hu ua L-ascorbic acid. Vitamin C muaj zog txo cov cuab yeej thiab yooj yim oxidized rau dehydrovitamin C, tab sis cov tshuaj tiv thaiv yog thim rov qab, thiab ascorbic acid thiab dehydroascorbic acid muaj tib lub cev muaj nuj nqi. Txawm li cas los xij, yog tias dehydroascorbic acid ntxiv hydrolyzed los tsim diketogulonic acid, cov tshuaj tiv thaiv yuav rov qab tsis tau thiab qhov ua tau zoo ntawm lub cev yuav ploj mus.

Daim ntawv thov
1. Vitamin C yog tsim los ntawm cov tshuaj tiv thaiv thiab collagen, kho cov ntaub so ntswg (xws li cov teebmeem redox), cov metabolism hauv phenylalanine, tyrosine, thiab folic acid, kev siv hlau thiab carbohydrates, synthesis ntawm cov rog thiab protein, kev saib xyuas ntawm lub cev tsis muaj zog, hydroxyl Antioxidant 5-hydroxytryptamine yog tsim nyog los tswj cov kev ncaj ncees ntawm cov hlab ntsha thiab cov hlab ntsha. Nyob rau tib lub sijhawm, vitamin C kuj muaj cov tshuaj tiv thaiv oxidation, tiv thaiv dawb radicals, thiab inhibits qhov tsim ntawm tyrosinase, thiaj li ua tiav cov nyhuv ntawm whitening thiab lightening me ntsis.
2. Nyob rau hauv tib neeg lub cev, vitamin C yog ib tug high-efficiency antioxidant siv los txo oxidative kev nyuaj siab ntawm ascorbate peroxidase sch. Muaj ntau cov txheej txheem biosynthetic tseem ceeb uas tseem xav tau cov vitamin C los koom.
3. Vim tias cov tsiaj nyeg feem ntau tuaj yeem tsim cov vitamin C los ntawm lub siab, tsis muaj teeb meem ntawm qhov tsis txaus; Txawm li cas los xij, qee yam tsiaj xws li tib neeg, primates, thiab groundhogs tsis tuaj yeem tsim cov vitamin C los ntawm lawv tus kheej thiab yuav tsum tau noj los ntawm zaub mov thiab tshuaj.
