20 Δεκ 2023 · Ascorbic acid as an antioxidant contributes to the maintenance of the vascular system, the reduction of atherogenesis through regulation of collagen synthesis, and the production of prostacyclin and nitric oxide. It reacts with compounds like histamine and peroxides to reduce inflammatory responses.
Vitamin C is an essential micronutrient for humans, with pleiotropic functions related to its ability to donate electrons. It is a potent antioxidant and a cofactor for a family of biosynthetic and gene regulatory enzymes.
2 Αυγ 2017 · It is involved in the first line of antioxidant defense, protecting lipid membranes, and proteins from oxidative damage. As a water soluble molecule, vitamin C can work both inside and outside the cells, and can neutralize free radicals and prevent free radical damage.
These include the importance of proper sample processing and reliability of assays to ensure that vitamin C measurements are accurate and precise (Levine et al., 1999b); the role of vitamin C as an antioxidant (Padayatty et al., 2003); and the chemistry and biology of pharmacologic (high dose) intravenously administered vitamin C (Levine et al.,...
Thus, vitamin C has diverse role as an antioxidant protecting the immune cells against intracellular ROS production during inflammatory response, acting as an enzymatic cofactor and maintaining tissue integrity and plays a crucial role in formation of skin, epithelial and endothelial barriers [185].
