Khoom Taw Qhia
3-O-ethyl ascorbic acid ether tseem hu ua vitamin C ethyl e lawv. Vitamin C tsis tuaj yeem nqus tau ncaj qha los ntawm daim tawv nqaij vim nws cov qauv nrog 4 pawg hydroxyl, thiab nws yooj yim oxidized ua kom tsis muaj xim, thiab nws siv los ua cov tshuaj pleev xim rau hauv cov tshuaj pleev ib ce yog txwv. Cov vitamin C ethyl e lawv npaj tau tom qab 3-hydroxyl hydrocarbylation yog cov vitamin C derivative tsis muaj xim, thiab tsis cuam tshuam rau nws cov khoom lom, yog li sau qhov sib txawv ntawm cov khoom zoo sib xws hauv khw. Cov kev tshawb fawb tau pom tias vitamin C ethyl e lawv yooj yim decomposed los ntawm enzymes tom qab nkag mus rau ntawm daim tawv nqaij los ua lub luag hauj lwm ntawm vitamin C.
Muaj nuj nqi
Anti-aging: Vitamin C tuaj yeem pab txo qis cov kab zoo thiab wrinkles, thiab txhim kho daim tawv nqaij firmness thiab elasticity.
