Free radical molecule, is unstable state, so the molecules are strongly captured by other elements of an electronic order to restore its balance, free radicals, "seize electronic" cause harm to humans, because free radicals "steal" may be the original electronic there are normal, healthy cells, healthy cells free radicals obtained by the electronic and hurt otherwise healthy cells, but also damage the body's normal functioning.

Sixteen electronic oxygen atoms around the core sixteen protons, this time showing neutral (steady state); state of oxygen in the molecule is very stable, and another oxygen atom or other atoms, sharing the external electronics, the formation of compounds . However, the stable molecule loses an electron, when becomes positively charged, unstable and reacted strongly to this molecule is a radical. Body of free radicals as the loss of an electron, will want to snatch an electron from another molecule to stabilize its structure, but it may take away from the original stable molecular electronics, resulting in another unstable free radicals, again and again, constantly molecular snatch electronics, so that fat corrupt the process, our body fat (for example: lens of the eye of fat) is no exception. Molecules naturally seek stability in this way, but the operation is not a natural human state, in the body, these positively charged molecules reacted strongly to snatch the negative balance in the cell membrane to form the hole; disrupt the protein, fat, nucleic acid structure, resulting in DNA mutations. Radicals can combine all of the body, Japanese scientists estimated daily average of about being a human cell, twenty thousand free radical attack!

Because human cells can not cope with every day, twenty thousand free radical attack than the body's antioxidant system load, free radicals have the opportunity to cause harm to humans. 
In the body's normal metabolic process, free radicals and oxidation of naturally occurring, and that the extra thousands of free radicals come from? Non-natural chemical composition over time caused by toxic pollution, the following substances may cause harmful molecules in vivo stability of the chemical reaction: alcohol, drugs, petrochemical substances, emissions, smoke, pesticides, chemical treatment, emotional stress, radiation and acid rain, etc. , is also possible that the food produced in the processing or cooking time, for now you should know how dangerous ignorance of the body's needs, to continue to make their body is premature aging (corruption), decomposition, death!

Because small molecules can be an endless supply of energy π water supply of electronics, so it can effectively eliminate free radicals, the water molecules energy π water contains divalent trivalent iron salt, hydrogen sulfate can contain trace elements of small molecules broken down into newborn hydrogen and oxygen. The biochemical point of view of science, 0 - represents the new single-gas, chemical and biological reactions have not yet entered the state, free radicals are positively charged ions; 0 + represents a single oxygen or oxygen molecules, water molecules break down the new energy π water with oxygen negatively charged, it will lead to two situations: (a) a new oxygen to free radical electron (b) the new ions are negatively charged, positively charged ions attracted by free radicals, oxygen combine to form O2, together with a carbon dioxide. Simply put, the new electronic or free radicals of oxygen free radicals combine to form oxygen molecules (O2), to neutralize dangerous free radicals. 
Small molecules of water can provide electronic energy π, then he will not become free radicals, which the body converts some of the extra electron of water supply an endless supply of electronics, healthy cells against free radicals to "steal" electrons directly to eliminate free radicals damage the body organs, to prevent disease, eliminate chronic diseases.
