维生素C

Vitamin C, also known as vitamin C, is a polyhydroxy compound with the chemical formula C6H8O6. Its structure is similar to glucose, and the two adjacent enol hydroxyl groups in the second and third positions of the molecule are easily dissociated to release H+, so it has the nature of acid, also known as L-ascorbic acid. Vitamin C has strong reducibility and is easily oxidized to dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function, but if dehydroascorbic acid is further hydrolyzed to produce diketogualoic acid, the reaction is irreversible and the physiological efficacy is completely lost. Vitamin C is an acidic white crystalline or crystalline powder. It is easily oxidized and turns yellow in humid air. 1 g of this product is soluble in about 3mL water, 30mL ethanol, 50mL absolute ethanol and 100mL glycerol, but insoluble in diethyl ether, benzene, trichloromethane, petroleum ether, oils and fats. Vitamin C is flammable and burns to produce irritating fumes.
