Top 10 High Antioxidant Foods While there are many ways to describe what antioxidants do inside the body, one definition of antioxidants is any substance that inhibits oxidation, especially one used to counteract the deterioration of stored food products or removes potentially damaging oxidizing agents in a living organism.

Antioxidants and Free radicals Antioxidants and Free radicals. Antioxidants are intimately involved in the prevention of cellular damage -- the common pathway for cancer, aging, and a variety of diseases. The scientific community has begun to unveil some of the mysteries surrounding this topic, and the media has begun whetting our thirst for knowledge.

- As the name implies, antioxidants are substances that are capable of counteracting the damaging, but normal, effects of the physiological process of oxidation in animal tissue. Antioxidants are nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions).They are believed to play a role in preventing the development of such chronic diseases as cancer, heart disease ,stroke, Alzheimer's disease, Rheumatoid arthritis, and cataracts.xidative stress occurs when the production of harmful molecules called free radicals is beyond the protective capability of the antioxidant defenses. Free radicals are chemically active atoms or molecular fragments that have a charge due to an excess or deficient number of electrons.

Origination Fees on a Vehicle For auto loans, origination fees are calculated as a percentage of the total loan, usually between 1 and 2 percent of the loan amount. If a lender takes a 2-percent fee for originating a loan, for example, the lenders will make $600 on a $30,000 loan. For leases, the leasing origination fee is a flat fee.

Oxidizing and Reducing Agents Oxidizing and Reducing Agents. An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.

Oxidizing Agent Definition - What does Oxidizing Agent mean? An oxidizing agent is a compound or element that is present in a redox (oxidation-reduction) reaction which receives electrons originating from a different species. The oxidant is a chemical compound which easily transfers atoms of oxygen or another substance in order to gain an electron. If one agent in the reaction releases oxygen or gains electrons or hydrogen, it is considered an oxidizer. The oxidizer is reduced as it takes on electrons. However, the reactant undergoes oxidation by letting its electrons be captured by the oxidizer. Oxygen is the eponymous example of an oxidizing agent.

Reduce inflammation effortlessly by taking these top antioxidants Antioxidants are organic compounds found in food especially in brightly colored vegetables and grains. Common antioxidants in food include: vitamin A, C and E; beta-carotene, lycopene and the trace mineral selenium.Antioxidants neutralize free radicals by donating an electron. However, the donating antioxidants become free radicals in the process with one exception, glutathione, which is created by the liver.ommon antioxidants in food include: vitamin A, C and E; beta-carotene, lycopene and the trace mineral selenium.

Redox Reactions Finally, two terms you may run across in the future are oxidizing agent (or oxidant) and a reducing agent (reductant). An oxidizing agent causes oxidation and is reduced in the reaction. A reducing agent causes the reduction in the redox reaction. The reducing agent is oxidized in the reaction.

What are Free Radicals? Free radicals, also known simply as radicals, are organic molecules responsible for aging, tissue damage, and possibly some diseases. These molecules are very unstable, therefore they look to bond with other molecules, destroying their health and further continuing the damaging process.

- The terms antioxidants and free radicals are being used more and more by nutritionists and other health professionals. Antioxidants are compounds that are thought to be good for you and free radicals are harmful.n general, antioxidants neutralize free radicals that are generated in the body and prevent damage to cell proteins, lipids and carbohydrates. Antioxidants can be water-soluble or lipid-soluble, thus some exist within the lipid or within the water portion of cells.

- Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.”. The body makes some of the antioxidants it uses to neutralize free radicals.These antioxidants are called endogenous antioxidants. However, the body relies on external (exogenous) sources, primarily the diet, to obtain the rest of the antioxidants it needs.he body makes some of the antioxidants it uses to neutralize free radicals.

Antioxidant Model of the antioxidant metabolite glutathione. The yellow sphere is the redox-active sulfur atom that provides antioxidant activity, while the red, blue, white, and dark grey spheres represent oxygen, nitrogen, hydrogen, and carbon atoms, respectively. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions.

Oxidizing agent In one sense, an oxidizing agent is a chemical species that removes an electron from another species. It is one component in an oxidation-reduction (redox) reaction. In the second sense, an oxidizing agent or an oxidizer is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate.

Antioxidant Properties of Vitamins Antioxidant Properties of Vitamins By: Dr. George Obikoya. A dietary antioxidant is a substance (commonly found in foods) that significantly decreases the harmful effects of reactive species, such as reactive oxygen and nitrogen molecules, that disrupt normal physiological function on a cellular level in humans.ecause of the widespread effects of oxidation in the body, it is possible that antioxidants protect against a wide array of other ailments, such as certain respiratory disorders. Asthma is characterized by chronic airway inflammation.

Sources of Antioxidants Antioxidants are vitamins and compounds that reduce the effects of oxidative stress on the human body. Oxidative stress can lead to the formation of free radicals, which through a chain reaction can lead to the growth of cancerous cells and tumors. Natural antioxidants can stop this chain reaction.

Antioxidants: In Depth Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases.
