Antioxidants are substances needed by the body. In the human body there are free radicals, a byproduct of the process of energy generation. On a certain number of free radicals is needed in order to help the white blood cells or leukocytes to destroy or take germs that enter the body.
Our blood at any time carry oxygen to the cells of the body. Oxygen helps cells convert nutrients into energy. Under normal conditions, the molecules in the cell has a complete electron pairs so stable. When in contact with oxygen, the molecule that loses electrons is oxidized. Unstable molecules are then transformed into what is called free radicals. Thus, free radicals are a natural product of metabolism of cells. Free radicals are a natural together with the air we breathe. Antioxidants are compounds that are able to delay, slow or inhibit the oxidation reactions to foods or medications which compounds are easily oxidized to other protected cells from free radicals.
Antioxidants are substances that neutralize free radicals because these compounds to sacrifice himself in order to oxidize so that other cells can be protected from free radicals, protecting cells from the harmful effects of reactive oxygen free radicals if it is related to the disease itself of free radicals which can be derived from the metabolism of the body or other external factors
Antioxidants are substances that can slow or prevent the oxidation process. This substance is able to significantly slow down or inhibit the oxidation of substances / elements that easily oxidized even in low concentrations. Antioxidants are also suitable defined as compounds that protect cells from the harmful effects of reactive oxygen free radicals when it comes to disease, free radicals can be derived from the body's metabolism as well as other external factors. Free radicals are substances that are unstable because they have unpaired electrons and electron pairs in the search for biological macro-molecules. Protein lipids and DNA from healthy human cells is a good source of electron pairs. Oxidizing conditions can cause damage to proteins and DNA, cancer, aging, and disease lainnya.Komponen chemicals that act as antioxidants are phenolic and polyphenolic compounds class. The class of compounds widely available in nature, especially in plants, and has the ability to capture free radicals.Antioxidants are found in many foods, such as vitamin E, vitamin C, and carotenoids.
