Area of Science:

  • Biochemistry
  • Pharmacology
  • Cell Biology

Background:

  • Inflammatory processes generate reactive oxygen species (ROS).
  • Intrinsic and extrinsic factors influence ROS levels.
  • Antioxidants play a role in managing ROS and oxidative stress.

Purpose of the Study:

  • To summarize antioxidant mechanisms against oxidative damage.
  • To outline oxygen activation in disease.
  • To explain the protective actions of antioxidants.

Main Methods:

  • Literature review on antioxidant mechanisms.
  • Summary of oxygen activation principles in diseases.
  • Outline of antioxidant functions (vitamin C, E, flavonoids).

Main Results:

  • Antioxidants, particularly phenolics like flavonoids, act as free radical scavengers.
  • Vitamin C and E demonstrate protective effects against oxidative damage.
  • Plant extracts containing flavonoids are utilized in natural medicine.

Conclusions:

  • Antioxidants are vital for mitigating oxidative stress in inflammatory conditions.
  • Understanding oxygen activation pathways is key to appreciating antioxidant roles.
  • Vitamins and flavonoids offer significant protection against cellular damage.
