Vitamin C (ascorbic acid) has several biological functions. Above all, it is essential for the synthesis of collagen and glycosaminoglycans, which are the building materials of all connective tissues, such as skin, blood vessels, tendons, joint and bone cartilages. Vitamin C is the coenzyme required for two groups of enzymes that catalyze the crosslinking of collagen fibers - lysyl hydroxylases and prolyl hydroxylases. As such, vitamin C is essential for wound healing and capillary health.
It also participates in the biosynthesis of carnitine, serotonin, and certain neurotransmitters, including norepinephrine.
Vitamin C is among the most potent antioxidants in humans and animals. It is a water-soluble antioxidant, which reacts directly with superoxide, hydroxyl radicals, and singlet oxygen.
Laboratory studies show that vitamin C completely protects plasma lipids and low density lipoproteins (LDL) against atherogenic peroxidative damage. In addition, vitamin C interacts with glutathione and alpha-lipoic acid, and regenerates vitamin E.
