Whakamahinga
Ko te waikawa ascorbic glucoside, e mōhiotia ana ko te VC glucoside, me te ingoa pūtaiao OAD-pyran glucosyl-L-ascorbic acid (2-OaD-glucopyranosyl-L-ascorbic acid, whakarāpopototia ko AA-2G), he mea hanga mai i te VC me te papatipu ngota whanaunga o te 338.27. Ko te ira rewa ko 158.5-159.5℃. Nā ngā ngoikoretanga o te VC pēnei i te kore pumau me te ngāwari o te waikura, kua puta mai te waikawa ascorbic glucoside, he hua whakakapinga mō te VC. Ka taea e ia te whakakapi i te VC hei waikawa waikawa, hei whakaiti, hei ārai mate, hei whakama me te whakaū, ā, he whānuitia te whakamahinga i roto i ngā mahi whakapaipai, kai me te rongoā.
I muri i te hurihanga o te waikawa ascorbic glucoside hei huaora C, ā, ka uru ki roto i ngā pūtau kiri, ka tino whakaitihia te hanganga o te melanin mā te aukati i te mahi a te tyrosinase. Mā te aukati i te tyrosinase ka heke te dopaquinone, he matū takawaenga i roto i te hanganga o te melanin. Ko tētahi atu painga ko te hurihanga o te dopaquinone hei levodopa i te wā kotahi, ka whakaiti i te melanin kua hangaia, ā, ka whakaitihia te tae kiri. 2. Ātete ki te kino o te UV me te aukati i te kino o te hihi ultraviolet ki ngā pūtau. I muri i te hurihanga o te waikawa ascorbic glucoside hei huaora C, ka taea e ia te whakaiti nui i ngā rauropi kore utu i hangaia e te hihi ultraviolet i roto i te kiri, ka tino whakaiti i te kino o te kiri, ā, ka whai wāhi tiaki hoki mō te kiri i roto i ngā hua pare rā.
Ko te waikawa ascorbic glucoside tētahi o ngā tāpiringa whakama kua whakaaetia e te Tari Hauora, ā, e mōhiotia ana ko ia te mea tino pumau o te huaora C. Koinei hoki te kai whakama e whakamahia whānuitia ana e ngā waitohu nui i tēnei wā. Hei tauira, ka whakamahia e L 'Oreal ngā matū C-glycoside me ētahi atu wāhanga hei ārai, hei rongoā rānei i ngā tohu o te koroheketanga o te kiri tinana, o te mata rānei. Ehara i te mea he pai te pānga whakama o te waikawa ascorbic glucoside, engari he pumau hoki ōna āhuatanga matū, ā, kāore e whakapataritari i te kiri. He whānuitia te whakamahinga i roto i ngā mea whakapaipai i te kāinga me tāwāhi, ā, kua mōhiotia e te marea. Kei te ripanga e whai ake nei ngā āhuatanga whakamahinga o ngā matū huaora C noa i roto i ngā mea whakapaipai.
