Dehydroascorbic acid (Vitamin C)

 
“Dehydroascorbate (Dehydroascorbic acid)”  

Dehydroascorbic acid (Dehydroascorbate)

    In our body, Dehydroascorbate (Dehydroascorbic acid), a diketogulonate lactone, is a readily and reversible oxidized form of ascorbic acid (vitamin C, ascorbate) and both forms exist in equilibrium in the body.

L-dehydroascorbate

    Dehydroascorbate (Dehydroascorbic acid) is actively imported into the endoplasmic reticulum of cells via glucose transporters. Dehydroascorbate (Dehydroascorbic acid) is trapped therein by reduction back to ascorbate by glutathione and other thiols.


    Therefore L-dehydroascorbic acid is a vitamin C compound much like L-ascorbic acid. The (free) chemical radical semi-dehydroascorbic acid (SDA) also belongs to the group of oxidized ascorbic acids. *

“Vitamin C (Ascorbate) Functions”  
    Our body, must ingest Vitamin C (Ascorbate) for survival. Vitamin C is an electron donor, and this property accounts for all Vitamin C's known functions. In our body, vitamin C as an electron donor is a potent water-soluble antioxidant.
