Oxidative stress is caused by the presence of any of a number of reactive oxygen species (ROS) which the cell is unable to counterbalance. The result is damage to one or more biomolecules including DNA, RNA, proteins and lipids. Oxidative stress has been implicated in the natural aging process as well as a variety of disease states:

• Neoplastic: Hematological and Solid Tumor
• Metabolic: Obesity and Diabetes
• Neurological: Alzheimer's and Parkinson's diseases
