It is gaining prominence as a model oxidant in small molecule and protein therapeutics for its ability to initiate oxidation reactions via both nucleophilic and free radical mechanisms. [ 2 ] 2,2′-azobis (2-amidinopropane) dihydrochloride has been used in experiments on linoleic acid subjected to induced oxidation with different combinations ...
Free Radical Biology and Medicine is a peer-reviewed scientific journal and official journal of the Society for Redox Biology and Medicine. The journal covers research on redox biology, signaling, biological chemistry and medical implications of free radicals , reactive species, oxidants and antioxidants.
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. [1] A free radical is any atom or molecule that has a single unpaired electron in an outer shell. [2] While a few free radicals such as melanin are not chemically reactive, most biologically relevant free radicals are highly ...
Free Radical Research, formerly Free Radical Research Communications, is an academic journal that publishes research papers, hypotheses, and reviews on free radicals, redox signaling, antioxidants, and oxidative damage. It is published by Informa Healthcare.
The lipid hydroperoxyl radical (LOO•) can also undergo a variety of reactions to produce new radicals. [citation needed] The additional lipid radical (L•) continues the chain reaction, whilst the lipid hydroperoxide (LOOH) is the primary end product. [6] The formation of lipid radicals is sensitive to the kinetic isotope effect.

It is a dark-colored crystalline powder composed of stable free radical molecules. DPPH has two major applications, both in laboratory research: one is a monitor of chemical reactions involving radicals, most notably it is a common antioxidant assay, [1] and another is a standard of the position and intensity of electron paramagnetic resonance ...
