Scientists have discovered the useful properties of free radicals

Previously it was thought that free radicals carry only destructive properties that accelerate the aging process and cell death. A recent study by researchers from McGill University, proves that in some cases, free radicals increase the life expectancy. Radicals, by their nature, are oxidants, unstable substances that have one unpaired electron.

At the time of contact of the free radical cells and is a violation of its chemical structure. Scientists have proven that it is not so simple. During the experiment on the worm Caenorhabditis elegans has been established that free radicals are involved in programmed cell death (apoptosis). This is a physiological process that protects the body against the formation of cancerous tumors and infections.

Free radicals increased apoptosis so that the protective properties of the cells were increased, then the average life expectancy of the cells was increased. Note, worms increase the concentration of free radicals was increased life expectancy.
