Protect Your Cells From Free Radicals

By Dr. Lorna Mistranski

Free radicals can best be explained by looking at them from a cellular level and all the various kinds of cells that the human body has.

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.

An atom is made up of a nucleus, proton, electrons, and neutrons and where the amount of protons (particles that are positively charged) in the nucleus is what determines how many electrons (particles with a negative charge) will surround the atom.

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

Bonding together with other atoms and sharing electrons to complete the outer most shell

The typical way an atom achieves maximum stability is sharing electrons with other atoms. This allows the conditions to for the atoms sustain the molecules in the most efficient way.

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.

The body is usually able to fight off free radicals unless it's empty of antioxidants or free radicals production accumulates too much, damage can occur. The older you get the more free radical damage occurs. - 17273
