Abstract

Oxygen is a vital substrate for aerobic energy generation in the biological systems of higher animals. However, minimal quantities of some toxic substances referred to as free radicals are generated during this biochemical process. These compounds have large capacity to oxidize biological structures, especially membranes rich in lipids and proteins, causing cellular necrosis. The recent growth in knowledge of free radicals and reactive oxygen species (ROS) in biology is producing a medical revolution that promises a new age of health. In fact, the discovery of the role of free radicals in chronic degenerative diseases is as important as the discovery of the role of micro-organisms in infectious diseases.
