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 ...
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.

Antioxidative stress is an overabundance of bioavailable antioxidant compounds that interfere with the immune system's ability to neutralize pathogenic threats. The fundamental opposite is oxidative stress, which can lead to such disease states as coronary heart disease or cancer.
“Coconut water contains antioxidants that may help neutralize harmful free radicals in the body and protect cells from oxidative stress,” explains Olszewski.
Antioxidants neutralize free radicals. Both are molecules that circulate in the body. ... Free radicals are produced by certain body functions, like metabolism, and also by exposure to harmful ...
Free radicals have an ominous name and a lot of people misunderstand them, their complex role in our bodies and how to manage them. Over the Counter: Connecting the dots on the role of free ...
Phosphites: Act by decomposing peroxides into non-radical products, thus preventing further generation of free radicals, and contributing to the overall oxidate stability of the polymer. Phosphites are often used in combination with phenolic antioxidants for syngeristic effects. Example: tris(2,4-di-tert-butylphenyl)phosphite [citation needed]
“Antioxidants are compounds that neutralize unstable molecules called free radicals. When free radical numbers get too high in the body, causing an imbalance, it leads to cellular and tissue ...
