It has recently been shown that high concentrations of dehydroascorbate (DHA), that is, the oxidized form of VitC, induce oxidative stress and cell death in cancer cells [193], thus refurbishing the interest in the use of supranutritional doses of VitC as anticancer.
In spite of increases of the ascorbate and dehydroascorbate levels, COJ consumption causes an increase of the DHA/AA ratio (83%) compared to baseline (72%).
Glutathione oxidised by ROS forms oxidased glutathione, whereas ascorbic acid oxidased by the same compound forms monodehydroascorbate (MDA) and dehydroascorbate (DHA).
Dehydroascorbate (DHA) is always generated during the rapid disproportionation of the MDHA radical and DHA is then reduced to AsA by the action of DHAR using GSH as the reducing substrate.
AA (Ascorbic acid), GSH (Reduced glutathione), GSSG (Glutathione disulfide), [H.sub.2][O.sub.2] (Hydrogen peroxide), MDA (Malondialdehyde), ROS (Reactive oxygen species), TBA (Thiobarbituric acid), TCA (Trichloroacetic acid), NBT (Nitroblue etrazolium), FW (Fresh weight), PAL (Phenylalanine ammonia lyase), DHAS (Dehydroascorbate), POX (Peroxidase), UV (Ultraviolet).
In addition, GSH also provides reducing capacity in several reactions such as reduction of dehydroascorbate to ascorbate and formation of deoxyribonucleotides by ribonucleotide reductase.
Two upregulated antioxidant proteins identified in this study, dehydroascorbate peroxidase (DHAR, spot 18) and ascorbate peroxidase (APX, spot 19), revealed significant accumulation of 3.4- and 3.1-fold in 100 [micro]M As treatments.
The AA in the testes is maintained in a reduced state by GSH dependent dehydroascorbate reductase in the testes.

These enzymes repair proteins damaged by oxidation, reduce dehydroascorbate, metabolize sulfur, ensure proper polypeptide chain folding, and regulate protein function.
