Ascorbic Acid, also known as Vitamin C, is a six-carbon lactone produced by plants and some animal species but not by humans and other primates.
- Protects cells against the damaging effects of radiation and oxygen radicals
- Increases the rate of mineralization in osteoblasts
- Involved in hydroxylation of proline and lysine
L-Ascorbic Acid is a calcium channel protein inhibitor and reduces Na+/Ca2+ exchange in cultured astrocytes. L-Ascorbic Acid modulates cyclic nucleotide levels in B and T cells inhibits apoptosis in cultured rat ovarian follicles.
Ascorbic acid functions as an enzymatic cofactor for multiple enzymes, serving as an electron donor for monooxygenases and dioxygenases. Ascorbic acid also functions as a powerful antioxidant, particularly in regards to reactive oxygen species.
L-Ascorbic Acid is used as an Antimicrobial and Antioxidant in foodstuffs. Reductant for the isolation of chloroplasts. It has an effect on the nonspecific immune system. Preserves nitric oxide (NO) which may help prevent endothelial dysfunction. It also helps prevent and reverse the oxidative damage done to proteins and lipids as a result of cigarette smoke.
