Free radicals and your health
We will try to explain as clearly as possible what actually free radicals and how they affect your health.
Dr. Denham Harmon became very famous for having "discovered" free radicals or, more precisely, to develop "free radical concept of aging."
Atom is then referred to as "free radicals", and very reactive. When the cells in the body against free radicals, reactive radicals that can cause damage to cells. According to Dr. Harmon theory of aging, cells continuously produce free radicals and free radical damage constant eventually killing the cell. When free radicals kill or damage enough cells in an organism.
What is free radicals?
Free radical is any atom or molecule that has "unpaired electrons" outside the ring. An "unpaired electrons" will always mean that there is an odd number because the "pair" of electrons over the even
Protons have a positive electric charge. Electrons have a negative electrical charge. Electrons move around the central mass of protons and neutrons. Neutrons have no electric charge. This word corresponds to "neutral."
After an atom has fewer electrons, with a negative electrical charge, the protons, with positive electric charge, the atom now has more positive charge than the negative electric charge - we would say that this atom, itself, was charged positif.Karena attract positively charged electrons are available, with a negative charge.
free radicals indiscriminately taking electrons from other atoms, which in turn alter other atoms into secondary free radicals, causing a chain reaction that can cause substantial biological damage.
Dr. Denham Harmon, MD, Ph.D., first proposed the theory of aging as the indiscriminate chemical re-activity of free radicals may lead to random biological damage. The idea has a lot of experimental success, and is now regarded as the main theory of aging. Dr. Harmon's theory implies that antioxidants such as vitamin C and vitamin E, which prevent free radicals from oxidation (release of electrons from) sensitive biological molecules, will slow the aging process. Dr. Harmon launched the theory by showing, for the first time, that feeding a variety of antioxidants to mammals extend their life spans.
What mechanisms by free radicals cause damage and disease?
Cell membranes made of unsaturated fat. Unsaturated fatty cell membrane molecules are highly vulnerable to free radicals which this destructive process and is ready to contribute to a chain reaction that is not controlled. Oxidative damage, another name for the chemical reactions that cause free radicals, can cause damage or even hardening of lipids, which make-up the cell wall. If the cell wall of hardened (lipid peroxidation) then it becomes possible for the cell to properly get its nutrients, get signals from other cells to perform actions (such as the firing of neurons) and many other cellular activities can be affected. In addition to the cell walls, other biological molecules are also susceptible to damage, including RNA, DNA and protein enzymes.
The main site of free radical damage is the DNA found in mitochondria. Mitochondria are small membrane-enclosed area of cells that produce the chemicals cells use energy. Mitochondria is the "energy factories" of cells. Each cell contains a large collection of molecules called DNA which provide chemical instructions for cell function. This DNA is found in the cell nucleus, which functions as a "command center" of the cell, and also in the mitochondria. Automated cell many nuclear DNA damage repair. However, in mitochondrial DNA can not be immediately repaired.
Free radicals increases in the activity and quantity of toxic metals crashed in the body. Thus, toxic metals cause free radicals. Several hundred years ago we did NOT have the burden of toxic metals in our bodies that we now do, and we also do not have such exposure to free radicals. If you remove toxic metals from the body, you then greatly reduces the activity and the amount of free radicals.
It is also clear that environmental agents to start trouble free radicals. Toxicity of lead, pesticides, cadmium, ionizing radiation, alcohol and smoke cigarettes all possible because of their ability to launch free radicals.
