Let us start with the basis: every matter consists of atoms. Atoms have a nucleus that is orbited by electrons, just as a satellites orbit our earth.
When atoms lose one of their electrons under certain conditions, they become "free radicals". They have a craving for electrons and are desperately trying to become complete again. Thus, they "tear" electrons of adjacent molecules and can damage them. Metabolic processes also take place in the cells of the body, where free radicals are formed by coupling and decoupling electrons.
How does oxidative stress affect the body?
Free radicals are not just bad For a long time scientists regarded these free radicals, also called ROS reactive oxygen species as "harmful" because of their electron raid. In the meantime, however, they found that they - with the right balance - also have beneficial effects. The research group around Dr. Simone Di Giovanni UCL London has now discovered in an experimental model of axon regeneration that free radicals are even needed for axonal regeneration.
