CONT

L'irrésistible affinité des radicaux libres pour un grand nombre de molécules pouvant résoudre leurs problèmes d'électrons célibataires et l'étonnante vélocité à laquelle ils opèrent, rendent les radicaux libres dangereux. Car en ajoutant ou en ôtant un électron à d'autres molécules, un radical libre va engendrer un autre radical libre dont les propriétés peuvent être destructrices.
