Antioxidant Rich Vitamins
January 23rd, 2011The most typical free radicals, a.k.a oxidant particles, are built on oxygen molecules. When one electron is lost they ravage an electron from other molecules. This then ruin the cell DNA and can change future generations even turning them carcenogenic. Here is a list of the most typical oxidizing compounds our bodies have to cope with, our body’s antioxidant systems, and the anti-oxidants that are important to our health.
The Villains
SUPEROXIDE This is mostly the first free immoderate formed and is an oxygen molecule that has lost an electron. The ruin starts here as most others come from the super oxide radical.
HYDROGEN PEROXIDE Formed by conversion of the superoxide radical, it can pass thru the cell surface and harm the fragile inner parts of the cell.
HYDROXYL RADICALS – These are the most unsafe of all free immoderate agents. Formed when superoxide and hydrogen peroxide react together, which causes an acute reaction ; they will attack any molecule around them.
LIPID PEROXY RADICALS created when oxygen attacks fatty acids in the cell surfaces. This is extremely commonplace because the fat in the surfaces is extremely reactive and is the choice of the oxygen molecules. This is the same reaction that causes fatty beef left in a warm room to turn rancid. In the lipid chain reaction the fatty molecules release more oxidizing agents. This chain reaction can spread across the surface of the cell destroying the basic function of the cell.
The Heroes
Our antioxidant systems work in two parts : the enzyme systems and the antioxidant vitamins. The enzymes work just about inside the cell while the vitamins can work both outside and inside of the cell. There are two main antioxidant systems in our body and anti oxidising agents work to keep them working.
SUPEROXIDE DISMUTASE ( SOD ) These are trace minerals that are composed of several forms which are used both outside and in different parts of the cell. They require different minerals as cofactors ( “helper molecules” that assist in biochemical transformations ), which completes the enzyme and helps it to function thousands of times more successfully.
GLUTATHIONE PEROXIDASE ( GP ) Requiring selenium as a cofactor, this works in several places within the cell. Even Though it helps SOD do a more complete job, it performs a function SOD can not ; prevent the scary hydroxyl immoderate from being formed.
You only have so many enzyme systems in apiece cell and as the oxidant ( free immoderate ) load builds it will at last outstrip those systems. The only way to reverse this harmful overload is to increase anti-oxidant nutrients to fight the free radicals.
VITAMIN C critical water-soluble ( something that can be dissolved in water ) anti oxidant vitamin that works industriously to protect the fatty cell surfaces. The liquid surrounding our cells is mostly water based. Here’s where Vitamin C is located working hard to neutralize free radicals before they can work their way into the fatty cell surface. C might also be found within the cells defending the water-soluble areas. It also plays a vital role with vitamin E, reviving E when it is rendered inactive after it has done its job ; like a battery charge.
VITAMIN E Our fat-soluble ( something that dissolves in fat or fat solvent agents ) antioxidant vitamin. Oxidant particles are drawn to fat, especially polyunsaturated fat. Vitamin E does astonishing things fighting with lipid peroxy radicals. The cell membranes are mostly polyunsaturated fat ; so it is important to have masses of E availability.
BETA-CAROTENE Is wonderful because it works in both fat- and water-soluble areas as a free immoderate destroyer.
Cells and cell surfaces need sufficient levels of these 3 nutrient elements to guard against harmful lipid oxidization. Areas between cells should also contain enough levels of these vitamins to prevent oxidant particles from reaching the cell membrane to begin with. Collaborating these anti-oxidant vitamins enhance the usefulness of the others.
