Anti-oxidants for better life

Anti-oxidants for better life
Our human body is a complex system which comprises various building up and breaking down processes, together called as metabolism. Not all the metabolic reactions in our body produce good things in a better amount for which free radicals stand out as a good example. When oxygen interacts with certain molecules within our body, a group of atoms with an odd number of electrons known as free radicals are formed. In terms of chemistry, a radical is defined as an atom, molecule or ion that has unpaired valence electrons. These free radicals in turn start chain reaction and cause damage or death to the cells as a result of oxidative stress. These free radicals can interact with various important molecules of the body including nucleic acids and can lead to deadly diseases, such as cancer.

To avoid such disaster mediated by free radicals, our human system has a protective mechanism conducted by a major class of compounds called as anti-oxidants. These anti-oxidants could be able to terminate these chain reactions by directly acting on free radicals or by interacting and removing free radical intermediates and by ceasing the oxidation reactions. The anti-oxidants are either present in the body in default (e.g. Glutathione or Vitamin C) or could be taken through food as a supplement. Plants are one of the known and wide sources for anti-oxidants in general. Vegetables and fruits are leading parts of the plants comprising anti-oxidant properties. It is hence very important for us to understand the requirement of anti-oxidants for our body in the form of food to protect ourselves from oxidative damages.
