) can be coupled to the glutathione reductase system to effect nicotinamide adenine dinucleotide phosphate (NADPH) oxidation.
The parts of the cells damaged are DNA, lipids and proteins that make up the cells.
This slows down the production of collagen and elastin, which is essential in keeping the skin firm and preventing wrinkling.
Because ascorbic acid is easily oxidized, it is used as a reductant in photographic developer solutions and as a preservative.
In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photo bleaching.
