Formation of one or more chemically reactive intermediate(s) as a result of modification of a molecule by the xenobiotic-metabolizing enzymes of liver and other organs.
Notes:
  1. This may lead to acute cell damage and recognition of the damaged cell by the immune system as non-self.
  2. The reactive intermediate can also act as a hapten.
