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.
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.
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 mechanisms in tissue injury. Lipid peroxidation induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination). Antioxidants play a crucial role in mitigating lipid peroxidation by neutralizing free radicals, thereby halting radical chain reactions. Key antioxidants include vitamin C and vitamin E. [8]
The formation of thiyl radicals in vivo primarily occurs through the action of various radicals on the amino acid cysteine incorporated into proteins. The rate of radical formation is highest with the OH · radical (k = 6.8 x 10 9 M −1 s −1) [3] and decreases through the H · radical (k = 6.8 x 10 9 M −1 s −1) [3] down to peroxyl radicals R-CHOO · (k = 4.2 x 10 3 M −1 s −1).

Redox Biology is an open-access peer-reviewed scientific journal and an official journal of the Society for Redox Biology and Medicine and the Society for Free Radical Research-Europe. [ 1 ] [ 2 ] The journal covers research on redox biology, aging, signaling, biological chemistry and medical implications of free radicals for health and disease.
The mitochondrial theory of ageing has two varieties: free radical and non-free radical. The first is one of the variants of the free radical theory of ageing. It was formulated by J. Miquel and colleagues in 1980 [1] and was developed in the works of Linnane and coworkers (1989). [2] The second was proposed by A. N. Lobachev in 1978. [3]
