  • Detalhes do produto

CAS 50-81-7  L(+)-Ascorbic acid, also known as vitamin C, is a polyhydroxy compound with the chemical formula C6H8O6. Its structure is similar to glucose. The two adjacent enol hydroxyl groups at positions 2 and 3 in the molecule are easy to dissociate and release H+, so it has the property of acid, also known as L-ascorbic acid. Vitamin C has strong reducibility and is easy to be oxidized to dehydro vitamin C, but its reaction is reversible, and ascorbic acid and dehydro ascorbic acid have the same physiological function. However, if dehydro ascorbic acid is further hydrolyzed to produce diketoguloic acid, the reaction will be irreversible and the physiological effect will be lost completely.
