Ascorbic acid (vitamin C) is an unusual antioxidant in that it donates a single reducing
equivalent, and the radical it forms, monodehydroascorbate, reacts preferentially with …

Vitamin C or ascorbic acid (AsA) is a naturally occurring organic compound with antioxidant
properties, found in both animals and plants. It functions as a redox buffer which can reduce …

Vitamin C readily scavenges reactive oxygen and nitrogen species and may thereby prevent
oxidative damage to important biological macromolecules such as DNA, lipids, and proteins …

Ever since the discovery of vitamin C (ascorbic acid), scientists have been intrigued as to
how ascorbic acid deficiency can lead to the diverse symptoms exhibited in scurvy. Only in …

Ascorbate has been demonstrated to be an effective antioxidant. It can act both directly, by
reaction with aqueous peroxyl radicals, and indirectly, by restoring the antioxidant properties …

Vitamin C in humans must be ingested for survival. Vitamin C is an electron donor, and this
property accounts for all its known functions. As an electron donor, vitamin C is a potent …

Vitamin C, ascorbic acid, has versatile functions in biological systems such as the facilitation
of collagen formation and iron absorption [1-6]. Vitamin C is a water-soluble vitamin and it is …

Ascorbic acid (vitamin C) is a water-soluble micronutrient required for multiple biological
functions. Ascorbic acid is a cofactor for several enzymes participating in the post …

An antioxidant is a substance that, when present at low concentrations compared to those of
an oxidizable substrate, significantly delays or prevents oxidation of that substrate. Many …
