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.
Character
CAS 50-81-7 L(+)-Ascorbic acid is white crystal or crystalline powder, odorless, sour, and gradually turns yellowish after a long time. It is easily soluble in water, acidic, slightly soluble in ethanol, and insoluble in chloroform or ether.
Function
CAS 50-81-7 L(+)-Ascorbic acid is necessary for the formation of antibodies and collagen, tissue repair (including some oxidation-reduction effects), metabolism of phenylalanine, tyrosine and folic acid, utilization of iron and carbohydrate, synthesis of fat and protein, maintenance of immune function, hydroxylation of 5-hydroxytryptamine, maintenance of vascular integrity, promotion of non heme iron absorption, etc. At the same time, vitamin C also has antioxidant, anti free radicals, and inhibition of tyrosinase formation, So as to achieve the effect of whitening and spot lightening.
