The cause of Destruction to the Body Defined
The best way to fully comprehend what free radicals are is to look at them from a cellular level. Here's a quick Physiology 101 lesson: The human body is made up of various kinds of cells.
Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds.
Atoms are made up of a nucleus, protons, electrons, and neutrons. The number positively charged particles (protons) in the nucleus of the atom is what determines how many negatively charged particles (electron) will surround the atom.
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.
The innermost shell is full when it has two electrons. When the first shell is full, electrons begin to fill the second shell. When the second shell has eight electrons, it is full.
The most significant factor in determining an atoms chemical behavior is the number of electrons in the outer shell.
An atom that has a full outer shell does not enter in chemical reactions. Atoms seek to reach a state of maximum stability by one of the following:
Eradicate or pick up electrons to fill or empty the shell
Bonding with other atoms to share electrons to complete the outer shell
Atoms regularly complete their outer shells by sharing electrons with other atoms. Sharing electrons allows the atoms that are bound together to satisfy the conditions of maximum stability for the molecule.
Usually when a split occurs, it never leaves the molecule with an odd, unpaired set of electrons. However, when bond does split, free radicals are created--they tend to move and react quickly to other compounds as they begin to attempt to capture as many electrons as they can to achieve maximum stability.
The most common way free radicals attack is by finding the closest molecule that is stable and from there they begin the process of stealing electrons. When the molecule that is attacked starts losing the electrons, it becomes a free radical as well. When this process begins, it creates a chain reaction in which the end result is a disruption of a living cell.
Free radicals will frequently arrive during metabolism and sometimes the body will even produce them to fight off viruses and bacteria. Free radicals also come from pollution such as radiation, cigarette smoke, and pesticides.
The body usually defends these free radicals well, however when antioxidants are not available or free radical damage becomes too excessive, cell damage can occur. The most significant importance to this free radical damage is that it accelerates the aging process in humans - 17268
