Free Radical

Free radicals are atoms or molecules with at least one unpaired electron (missing one or more protons last ring atom). These molecules are very unstable and go in search of the electron lost by stealing an electron to the neighboring molecules, giving rise to other radicals. Is thus to give rise to a chain reaction that long can cause dangerous damage.

Normally free radicals are formed in our body when we turn oxygen into energy (oxidation). The 95% of the oxygen we breathe is transformed into energy; the remaining instead gives rise to free radicals. This is a normal process that our body, if it is healthy, can handle themselves. Furthermore, a minimal amount of free radicals is useful to eliminate germs and bacteria from our body.

But free radicals can also be formed by exogenous factors other than biochemical oxidation.
 

For example, smoking, alcohol, drugs, medicines, rhinestone-being as intense and prolonged exercise, sunlight, and smog and polluting gases. These are some of the most important factors that increase the number of free radicals that are formed in the body and that we are not able to completely neutralize alone.

The effect of the continuous formation of free radicals is evident especially in the premature aging of cells and in the onset of various serious diseases such as cancer but also in Parkinson's disease and Alzheimer's.

To guard against an excessive number of free radicals must take antioxidants such as vitamin E, vitamin C, carotenoids, etc.. etc..

In this blog you will find a lot of information that I have collected among the different books that I have read and among the various information I find on the internet.
