D-Isoascorbic acid muaj qhov zoo uas Vc tsis muaj

D-Isoascorbic acid Erythorbic acid tuaj yeem siv los ua zaub mov los tiv thaiv oxidant; raws li cov khoom pab ntawm cov tshuaj los yog cov khoom siv kho mob; raws li stabilizer ntawm chemical raw khoom; tshwj tsis yog cov pa oxygen, thiab tiv thaiv corrosion, thiab tsuas yog cov kuab tshuaj ntawm cov khoom tseem ceeb; raws li electrolytes ntawm electrolytic thiab plating; raws li cov hlau micro-hmoov ntawm ntau lawm thiab hnyav hlau ntawm recycling. Tsis tas li ntawd, erythorbic acid kuj tseem siv rau kev tsim cov tshuaj textile, cov khoom siv hauv tsev thiab kev lag luam chemical niaj hnub.

Taw qhia

D-isoascorbic acid yog lub ntuj, ntsuab thiab muaj txiaj ntsig zoo rau cov zaub mov antioxidant, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ruaj ntseg ntawm cov zaub mov thiab ncua sij hawm cia. Raws li ib qho isomer ntawm Vc, D-isoascorbic acid muaj ntau qhov zoo sib xws hauv cov khoom siv tshuaj nrog Vc, tab sis raws li cov tshuaj antioxidant, nws muaj qhov zoo uas Vc tsis muaj. Ua ntej tshaj plaws, nws cov oxidation kuj zoo dua li ntawm Vc. Yog li ntawd, thaum siv VcChemicalbook, nws tuaj yeem tiv thaiv cov khoom siv tshuaj ntawm Vc, thiab muaj txiaj ntsig zoo hauv kev txhim kho cov khoom siv tshuaj, thaum tiv thaiv cov xim ntawm Vc. Qhov thib ob, kev nyab xeeb yog siab, tsis muaj qhov seem hauv tib neeg lub cev, thiab lub cev koom nrog cov metabolism tom qab noj, uas tuaj yeem hloov pauv mus rau Vc. Nyob rau hauv xyoo tas los no, nws tau siv rau Vc ntsiav tshuaj, Vc Yinqiao ntsiav tshuaj thiab Vc cov khoom noj qab haus huv raws li ib yam khoom pab rau cov tshuaj, thiab tau ua tiav cov txiaj ntsig zoo.
