Description. Dehydroascorbic acid is the oxidized form of vitamin C. Reduced Vitamin C concentrations in the brain exceed those in blood by 10 fold. Dehydroascorbic acid readily enters the brain and is retained in the brain tissue in the form of ascorbic acid (ascorbic acid is not able to cross the blood-brain barrier).escription.
