Ukusetshenziswa
I-ascorbic acid glucoside, eyaziwa nangokuthi i-VC glucoside, enegama lesayensi elithi OAD-pyran glucosyl-L-ascorbic acid (2-OaD-glucopyranosyl-L-ascorbic acid, efushaniswe ngokuthi i-AA-2G), iyi-derivative ye-VC enesisindo sama-molecule esingu-338.27. Indawo yokuncibilika ingu-158.5-159.5℃. Ngenxa yobubi be-VC njengokuqina okungekuhle kanye nokushiswa kalula, i-ascorbic acid glucoside, umkhiqizo othatha indawo ye-VC, itholakale. Ingathatha indawo ye-VC njenge-acidulant, i-reducing agent, i-antioxidant, i-bleaching agent kanye ne-stabilizer, futhi isetshenziswa kabanzi ezimweni zokugcoba, zokudla kanye nemithi.
Ngemva kokuba i-ascorbic acid glucoside iguqulwe ibe yi-vitamin C futhi ingene emangqamuzaneni esikhumba, inciphisa kakhulu ukwakheka kwe-melanin ngokuvimbela umsebenzi we-tyrosinase. Ukuvinjelwa kwe-tyrosinase kuholela ekunciphiseni kwe-dopaquinone, okuyisici esiphakathi ekwakhiweni kwe-melanin. Enye inzuzo eyengeziwe ukuthi iguqula i-dopaquinone ibe yi-levodopa ngasikhathi sinye, inciphise i-melanin esivele yakhiwe futhi ngaleyo ndlela inciphise umbala wesikhumba. 2. Melana nomonakalo we-UV futhi uvimbele umonakalo wemisebe ye-ultraviolet emangqamuzaneni. Ngemva kokuba i-ascorbic acid glucoside iguqulwe ibe yi-vitamin C, inganciphisa kakhulu ama-free radical akhiqizwa yimisebe ye-ultraviolet esikhumbeni, inciphise kakhulu umonakalo wesikhumba futhi idlale indima yokuvikela isikhumba emikhiqizweni ye-sunscreen.
I-Ascorbic acid glucoside ingenye yezithasiselo zokwenza mhlophe ezivunyelwe uMnyango Wezempilo futhi iqashelwa njenge-derivative ezinzile kakhulu ye-vitamin C. Futhi iyisithako sokwenza mhlophe esisetshenziswa kakhulu yimikhiqizo emikhulu njengamanje. Isibonelo, i-L 'Oreal isebenzisa i-C-glycoside derivatives ngokubambisana nezinye izingxenye ukuvimbela noma ukwelapha izimpawu zokuguga emzimbeni noma esikhumbeni sobuso. I-Ascorbic acid glucoside ayigcini nje ngokuba nomphumela omuhle wokwenza mhlophe, kodwa futhi inezakhiwo zamakhemikhali ezizinzile futhi ayicasuli isikhumba. Isetshenziswa kabanzi ezimonyweni ekhaya nakwamanye amazwe futhi iye yaqashelwa umphakathi. Ithebula elilandelayo libala izimo zokusetshenziswa kwe-vitamin C derivatives evamile ezimonyweni.
