How does a free radical works?

Free radicals are unstable and seek out other electron with whom they could pair up.
They will act, in our body, as terrorists, stealing electrons of other molecules to pair up.
They can attack DNA, enzymes, proteins, cell membranes...

Damages that result from the attack of free radicals:

  • Dysfunction in the replication of the DNA, mutation and cancer.
  • Disruption of the normal cell activities which could lead to the death of the cell.
  • Destruction of cell membranes, which can lead to the hardening and thickening of arteries and eventually heart attacks and strokes.
  • Alteration of the collagen, which result in stiffness in the tissue.
