Antioxidant and pro-oxidant properties of ascorbic acid and gallic acid

The antioxidant and pro-oxidant properties of ascorbic acid (AA) and gallic acid (GA) were investigated. AA and GA, at a concentration of 1.65 mM, accelerate the oxidation of deoxyribose induced by Fe 3+ ¨CEDTAJH 2 O 2. The reducing power of these two compounds increased upon increasing the concentration.

ascorbic acid: the chemistry underlying its antioxidant properties

Ascorbic acid: The chemistry underlying its antioxidant properties

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 radicals instead of with non-radical compounds.

These antioxidants might provoke mild oxidative stress due to their prooxidative properties (). Alpha-tocopherol is also known as a potent antioxidant and harmful prooxidant in high concentrations. When reacting with ROS, it becomes a radical itself, and if there is not enough vitamin C for its regeneration, it remains in the reactive state ( 8 , 9 ).

The antioxidant and pro-oxidant activity of vitamin C and trolox in vitro: a comparative study - PubMed

The antioxidant and pro-oxidant properties of ascorbic acid (vitamin C) and the water-soluble analogue of alpha-tocopherol (trolox) were compared. Trolox has advantages over alpha-tocopherol, the latter being only lipid-soluble due to the presence of a carboxyl group in lieu of a phytol chain which imparts trolox with water solubility.
