How Cells Function in the Body is the Key to Youth

By Dr. Lorna Mistranski

The best way to fully comprehend what free radicals are is to look at them from a cellular level in that the human body is made up of all kinds of cells.

The chemical bond of a cell is comprised of various types of molecules that are held together with one or more atom.

Atoms are comprised of protons, neutrons, and electrons whereby the total amount of protons that are in the nucleus determine how many electrons will surround them.

The role of the electrons is to manage chemical reactions that occur inside the atom as well as the substances that makes the atoms form molecules. Much like planets, electrons revolve around 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.

A substance that has a full outer shell tends not to enter in chemical reactions. Ultimately, atoms seek to reach a state of maximum stability, an atom will try to fill its outer shell by:

Adding or dropping electrons that will either fill or empty the atom's shell

Bonding with other atoms to share electrons to complete the outer 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.

Often, the bonds that the atoms form remain in tact so that maximum stability is maintained. However, when these bonds do tear, the highly unstable free radical is born and swiftly seeks to make itself more stable.

The ideal way free radicals attack is by locating the nearest molecule they can find that has achieved maximum stability and start stealing electrons. Once a molecule is attacked, it too becomes a free radical. This process creates a chain reaction that continues until it causes cells to become damaged.

The process of metabolism is frequently when free radicals occur and sometimes even when fighting off viruses and bacteria. Other producers of free radicals derive from pollution, cigarette smoke, radiation, and pesticides.

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. - 17274
