We Can Slow Down the Aging through Antioxidants Health Articles | May 31, 2017

Free radicals are natural nanoparticles which are doing their part well defined in the human cell, but then they must be annihilated or eliminated to not destroy the cell or another part of our body. It has been shown that residual free radicals in the body are responsible for the aging. The role to annihilate them is ful-filled by the antioxidants.



Introduction


Antioxidants are chemical compounds with many and varied applications. Naturally present in our diet Manchester City FC Jersey , through fruits, vegetables, tea or red wine, they are recognized to be good for health (McCall and Frei, 1999). In fact, antioxidants protect our body's proteins and nucleic acids from oxidation. In the industry, antioxidants are also used as food additives to increase the shelf life of food. They are also present in the packaging or the wheels of cars because they prevent synthetic materials from becoming crumbly and brittle. Finally, in the cosmetics industry Jordan Henderson Jersey , creams containing antioxidants are known for their anti-aging properties. An antioxidant is a molecule that decreases or prevents the oxidation of other chemicals. Oxidation is part of an oxidation-reduction reaction that transfers electrons from a substance to an oxidizing agent. This reaction can produce radicals that cause destructive chain reactions (Knight, 2000; Kowald and Kirkwood, 1996; Aversa et al., 2016 a-o, 2017 a-e).


However, whatever the field of application, the unstable nature of antioxidants is a problem: the molecules degrade rapidly and have a particularly limited power of action over time. The research team of Yiannis Deligiannakis, a visiting professor at the Institute of Process Engineering at the Swiss Federal Institute of Technology in Zurich (ETHZ) Mohamed Salah Jersey , has developed a nanoantioxidant with enhanced stability (Deligiannakis et al., 2012). This discovery is published in the journal ACS Applied Materials & Interfaces.


An antioxidant is a molecule that decreases or prevents the oxidation of other chemicals. Oxidation is part of an oxidation-reduction reaction that transfers electrons from a substance to an oxidizing agent. This reaction can produce radicals that cause destructive chain reactions. Antioxidants are able to stop these chain reactions by reducing with the radicals and thus annihilating their action. These properties are found in the families of thiols and phenols (Alexeyev et al., 2004; Allen and Coombs, 1980; Ames, 1989).


Although oxidation reactions are necessary for life, they can also be destructive: plants and animals use and produce many antioxidants to protect themselves, such as glutathione, vitamin C and vitamin E Sadio Mane Jersey , or enzymes such as Catalase, superoxide dismutase and certain peroxidases. A deficiency or absence of production of antioxidant enzymes leads to oxidative stress that can damage or destroy the cells. Similarly, our body is capable of producing, from the amino acid cysteine, a powerful antioxidant, α-lipoic acid, also called lipoate.


Oxidative stress has been implicated in the pathogenesis of many human diseases, the use of antioxidants in pharmacology is therefore much studied to treat especially stroke and neurodegenerative diseases (Ahmed and Tollefsbol Roberto Firmino Jersey , 2001; Anisimov, 2001; Artandi, 2006; Austad, 1993; Beckman and Ames, 1998; Besedovsky and Del Rey, 1996; Blackburn, 2000; Cadenas and Davies, 2000; Campisi Virgil van Dijk Jersey , 1997; Cong et al., 1999; Daynes and Araneo, 1992; Dirks and Leeuwenburgh, 2006; Fabris, 1991; Finkel and Holbrook, 2000; Franceschi, 1989; Hayflick, 2004; Holliday Liverpool FC Jersey , 2006; Huerre and Gounon, 1996; Kanungo, 1975; Wick et al., 1999).


However, it is not yet known whether oxidative stress is the cause or consequence of these diseases. Antioxidants are also important ingredients of dietary supplements in order to maintain health and prevent certain diseases, such as cancer or coronary heart disease. Although studies suggest that antioxidant supplements are beneficial to health, large clinical studies have not found any particular benefits and have even found that excess antioxidant supplements (or supplements) negative .
