Fenton reaction

Fen·ton re·ac·tion

1. the use of H2O2 and ferrous salts (Fenton reagent) to oxidize α-hydroxy acids to α-keto acids or to convert 1,2-glycols to α-hydroxy aldehydes;
2. the formation of OH·, OH-, and Fe3+ from the nonenzymatic reaction of Fe2+ with H2O2; a reaction of importance in the oxidative stress in blood cells and various tissues.

More research produced the answer: Vitamin C induced what is known as a Fenton reaction, causing iron to react with other molecules to create reactive oxygen species that kill the TB bacteria.
The paper is titled, "Mycobacterium tuberculosis is extraordinarily sensitive to killing by a vitamin C-induced Fenton reaction.
After further research, the team found vitamin C kills the virus by inducing what is known as a Fenton reaction.
21-22) Specifically, the Fenton reaction involves transition metal cations, usually ferric or cupric ions, being reduced to ferrous or cuprous ions by a reducing agent such as vitamin C.
dGlyage showed in vitro its ability to interact with Cu2+, preventing DNA damage caused by the OH generated by Fenton reaction.
It was concluded that rutin and quercetin are able to suppress free radical processes at three stages: the formation of superoxide ion, the generation of hydroxyl (or cryptohydroxyl) radicals in the Fenton reaction and the formation of lipid peroxy radicals.
It also adds a section on non-specific methods for the destruction of hazardous organic chemicals, including potassium permanganate oxidation and advanced oxidation processes, such as the Fenton reaction and photolysis.
Alternatively, hydroxyl radicals can be generated through the Fenton reaction formed by the oxidation of ferrous salts in the presence of hydrogen peroxide.
The scavenging activity for hydroxyl radicals was measured with Fenton reaction (Sadasivam and Manikam, 1992).
On the other hand, the Fenton reaction depends on the type of zeolite, suggesting that the surface structure of the iron on the zeolite plays an important role (Fach et al.
The CMFR system is designed to simulate the chemistry employed by brown-rot fungi in producing a "sustained" Fenton reaction to degrade and/or modify wood.
