Ascorbate glucoside, also known as VC glucoside, scientific name O-A-D-glucopyranosyl-L-Ascorbicacid (2-O-a-D-glucopyranosyl-L-ascorbicacid, abbreviated as AA-2G), is a derivative of VC, The relative molecular weight is 33chemical book8.27, and the melting point is 158.5 ~ 159.5ºC. Due to the poor stability of VC, easy to be oxidized and other shortcomings, the substitute product of VC is derived, ascorbate glucoside, which can replace VC as acid agent, reducing agent, antioxidant, bleach and stabilizer, and is widely used in cosmetics, food and medicine and other fields.
The content of melanin in human skin determines the color of skin. Cooline is the main raw material for the production of melanin. Tyrosinase is the rate-limiting enzyme in the pathway of tyrosine synthesis, which mainly affects the production of melanin by affecting the conversion of tyrosine into dopa Chemicalbook and the oxidation of dopa to dopa quinone. The mechanism of ascorbate glucoside whitening is to inhibit the production of melanin by inhibiting the activity of tyrosinase with L-cooline as the substrate.
