The human body is comprised of various kinds of cells and by looking at the body from this perspective is the best way to comprehend what free radicals are.

Cells are comprised of various types of molecules and these molecules consist of one or more atoms of one or more elements held together by a chemical bond.
Electrons are responsible for the chemical reactions that take place inside the atom as well as the substance that holds the atom together to form molecules. Electrons orbit the atom in one or more shells.
A atom is considered full when two electrons occupy the innermost layer. When the second layer is filled with electrons, the process starts all over again

The most important thing in determining the structural characteristic of an atom is the number of electrons in the outermost shell.
Picking up or dropping electrons that will either occupy or leave the outer shell
Adding or dropping electrons that will either fill or empty the atom's shell
Attaching to other atoms in a attempt to share electrons to have a complete outer shell
The most common way atoms achieve stability is with sharing electrons with other atoms. In this way the atom is able to achieve maximum stability.
Most of the time, these bonds do not tear apart in a way that leaves an atom with an odd, unpaired electron. When this does occur however, free radicals are formed; they are very unstable and react swiftly with other compounds in attempt to gain the needed electrons for stability.
Free radicals like to attack by locating the closest cell that has maximum stability and begins to steal electrons. Eventually these attacked molecules become free radicals themselves. The process will continue until eventually cellular damage occurs.
Common times when free radicals occur are during metabolism as well as when the body is fighting off bacteria or viruses. Pollution, cigarette smoke, radiation, and pesticides are other times when free radicals can occur.
Typically, the body is able to handle free radicals, but if antioxidants are unavailable, or if the free-radical production becomes excessive, damage can occur. Most importantly is that free radical damage accumulates with age. - 17268
