Free Radical Theory: A Review
نویسنده
چکیده
Aging can be loosely defined as the accumulation of changes within an organism over time. Aging is a complex, poorly understood, and multi-factorial process. It is generally regarded as progressive, irreversible, deleterious, and endogenous in nature [1]. Over 300 scientific theories seeking to explain the specifics of the process of aging have been posited. Yet, despite the vast amount of research, the plethora of competing theories, and the volumes of related literature, firmly established primary causes of biological aging remain unclear [2,3].

متن کاملTrends in oxidative aging theories.
The early observations on the rate-of-living theory by Max Rubner and the report by Gershman that oxygen free radicals exist in vivo culminated in the seminal proposal in the 1950s by Denham Harman that reactive oxygen species are a cause of aging (free radical theory of aging). The goal of this review is to analyze recent findings relevant in evaluating Harman's theory using experimental resul...
متن کاملA Theoretical Study on the Structure-Radical Scavenging Activity of Some Hydroxyphenols
Antioxidants are made for the struggle and reconstruction of the damaged cells, because of their ability in destroying the free radicals. On account of their importance, a theoretical procedure was applied for the study of the molecular structure and radical scavenging activity of six hydroxyphenols which have been introduced as antioxidant compounds. All geometry structures were optimized by M...
متن کاملMitochondria, Oxidants, and Aging
The free radical theory of aging postulates that the production of intracellular reactive oxygen species is the major determinant of life span. Numerous cell culture, invertebrate, and mammalian models exist that lend support to this half-century-old hypothesis. Here we review the evidence that both supports and conflicts with the free radical theory and examine the growing link between mitocho...
