Erythorbic Acid | 89-65-6 : kuv
Khoom Description
Erythorbic Acid los yog erythorbate, yav tas los hu ua isoAscorbic Acid thiab D-araboascorbic acid, yog ib qho stereoisomer ntawm ascorbic acid.Erythorbic acid, molecular mis C6H806, txheeb ze molecular mass 176.13. Dawb mus rau daj daj crystals uas zoo nyob ruaj khov nyob rau hauv cov huab cua nyob rau hauv qhuav lub xeev, tab sis deteriorate sai heev thaum raug rau huab cua nyob rau hauv kev daws. Nws cov khoom antioxidant zoo dua li ascorbic acid, thiab tus nqi pheej yig. Txawm hais tias nws tsis muaj cov nyhuv physiological ntawm ascorbic acid, nws yuav tsis cuam tshuam qhov nqus ntawm ascorbic acid los ntawm tib neeg lub cev.
Thiab nws cov khoom siv tshuaj muaj ntau yam zoo sib xws nrog Vc, tab sis raws li cov tshuaj tiv thaiv antioxidant, nws muaj qhov zoo tshaj plaws uas Vc tsis muaj: Ua ntej, nws yog qhov zoo tshaj rau cov tshuaj tiv thaiv oxidation dua Vc, yog li ntawd, tov cov Vc, nws tuaj yeem tiv thaiv tau zoo. khoom Vc tivthaiv hauv kev txhim kho cov khoom muaj txiaj ntsig zoo heev, thaum tiv thaiv Vc xim. Thib ob, kev ruaj ntseg dua, tsis muaj qhov seem hauv tib neeg lub cev, koom nrog cov metabolism tom qab nqus los ntawm tib neeg lub cev, uas tuaj yeem hloov mus rau Vc ib nrab. Nyob rau hauv xyoo tas los no, Suav tshuaj siv nws raws li cov ntaub ntawv ntxiv tau siv hauv Vc zaj duab xis, Vc Yinqiao-Vc, thiab cov khoom siv kho mob, thiab tau txais cov txiaj ntsig zoo.
