Question

Which water-soluble vitamin can regenerate vitamin e after it has been oxidized?

Answer 1

Vitamin C is the water soluble vitamin that can regenerate vitamin E after it has been oxidized. Because vitamin C is an acid, it is reasonably stable in acidic solutions, but in neutral or basic solutions it is easily and rapidly oxidized by dissolved oxygen. The oxidation of vitamin C, Ascorbic acid, is brought about by the loss of two hydrogen atoms as the vitamin is converted to dehydroascorbic acid. Vitamin C functions as antioxidant, assists in synthesis of collagen, a component of the connective tissue, synthesis of DNA, bile, neurotransmitters, thyroid and other hormones.
