Mitochondrial Production of Perhydroxyl Radical (HO2 • ) as Inducer of Aging and Age-Related Pathologies
All organisms age, in the search of the universal mechanisms of aging Barja analyzed results obtained with various species of mammals and birds and concluded that only two known factors correlate in the right sense (inversely) with animal longevity in vertebrates: the long life span is associated with (a) low rates of mitochondrial reactive oxygen species production, and (b) low degree of fatty acid polyunsaturation of cellular membranes including the mitochondrial ones [Barja (2014) Prog Mol Biol Transl Sci. 127:1-27].
The Role of Nutrition in Fighting Free Radicals
This paper aims to review in literature the main mechanisms of oxidative stress, pointing out the major formed metabolites, the mechanisms of cell damage and major antioxidants. Oxygen is essential to human life. The formation of free radicals (FR) is closely related to oxygen consumption, a mechanism that occurs with an incomplete reduction of this molecule.
