The CC Formula
Reactive Oxygen Species (ROS) is a phrase used to describe a number of reactive molecules and free radicals derived from molecular oxygen.
The production of oxygen-based radicals is the bane to all aerobic species.
Oxidation is the cause of Free Radicals, this happens when an electron is knocked out of a chemical bond.
These highly reactive free radicals will interact with and damage healthy molecules. Oxidative stress occurs when the destructive power of free radicals spreads from one cell to surrounding cells inflicting widespread damage.
