Ukusetyenziswa
I-ascorbic acid glucoside, ekwaziwa ngokuba yi-VC glucoside, enegama lesayensi elithi OAD-pyran glucosyl-L-ascorbic acid (2-OaD-glucopyranosyl-L-ascorbic acid, efinyeziweyo njenge-AA-2G), sisiphumo se-VC esinobunzima beemolekyuli obuyi-338.27. Indawo yokunyibilika yi-158.5-159.5℃. Ngenxa yeengxaki ze-VC ezifana nokuzinza okungalunganga kunye nokuxinana okulula, i-ascorbic acid glucoside, imveliso ethatha indawo ye-VC, ifunyenwe. Ingathatha indawo ye-VC njenge-acidulant, i-reducing agent, i-antioxidant, i-bleaching agent kunye ne-stabilizer, kwaye isetyenziswa kakhulu kwiindawo zokuthambisa, zokutya kunye namayeza.
Emva kokuba i-ascorbic acid glucoside iguqulwe ibe yi-vitamin C ize ingene kwiiseli zolusu, inciphisa kakhulu ukwakheka kwe-melanin ngokuthintela umsebenzi we-tyrosinase. Ukuthintelwa kwe-tyrosinase kukhokelela ekunciphiseni i-dopaquinone, eyinto ephakathi ekuvelisweni kwe-melanin. Enye inzuzo eyongezelelweyo kukuba iguqula i-dopaquinone ibe yi-levodopa ngaxeshanye, inciphisa i-melanin esele yenziwe kwaye ngaloo ndlela inciphisa umbala wolusu. 2. Ukumelana nomonakalo we-UV kunye nokuthintela umonakalo wemitha ye-ultraviolet kwiiseli. Emva kokuba i-ascorbic acid glucoside iguqulwe ibe yi-vitamin C, inokunciphisa kakhulu ii-free radicals eziveliswa yimitha ye-ultraviolet eluswini, inciphise kakhulu umonakalo wolusu kwaye idlale indima yokukhusela ulusu kwiimveliso ze-sunscreen.
I-Ascorbic acid glucoside yenye yezongezo zokwenza mhlophe ezivunyiweyo liSebe lezeMpilo kwaye ibonwa njengeyona nto izinzileyo kwi-vitamin C. Ikwayeyona nto isetyenziswa kakhulu ekwenzeni mhlophe ziinkampani ezinkulu okwangoku. Umzekelo, i-L 'Oreal isebenzisa i-C-glycoside derivatives ngokubambisana nezinye izinto ukuthintela okanye ukunyanga iimpawu zokwaluphala emzimbeni okanye eluswini lobuso. I-Ascorbic acid glucoside ayinayo nje kuphela impembelelo entle yokwenza mhlophe, kodwa ikwanazo neepropati ezizinzileyo zeekhemikhali kwaye ayicaphukisi ulusu. Isetyenziswa kakhulu kwizithambiso ekhaya nakwamanye amazwe kwaye iye yaqatshelwa luluntu. Le theyibhile ilandelayo idwelisa iimeko zokusetyenziswa kwe-vitamin C derivatives eqhelekileyo kwizithambiso.
