The body is made up many different types of cells consisting of many different types of molecules. These molecules consist of one or more atoms of one or more elements joined by a chemical bonds. Atoms consist of a nucleus,made up of a combination of neutrons and protons, circled by 1 or more electrons which form an outer shell. Protons have a positive charge and their number determines the number of electrons that surrounding the atom nucleus generally co-existing in pairs.
Electrons are involved in chemical reactions and are what bonds atoms together to form molecules. The number of electrons that form part of a molecule is important since it is what decides to a large extent the chemical behavior of that molecule. Basically, matter that has particles consisting of paired electrons will not react chemically. Because the nature of atoms is to find a state of maximum stability, particles and atoms that have un-paired electrons in their surrounding shell will attempt to 'steal' other electrons to pair them up with, either gaining them from other particles or by bonding with other particles to share electrons - this is a chemical reaction.
Electrons are positively charged and when they move between molecules so the charge of those particles becomes changed as well. This process of a particle losing some charge is termed 'oxidation' and theoretical change in the charge of a particle is referred to as the change in its oxidation state. When the process of oxidation in the human body, or in any other organic matter, causes tissue damage then this is often referred to as oxidative stress.
Free Radicals
The term 'free radical' is a chemical term and describes a particle or atom that has one or more unpaired electrons in its outer shells. These are unstable because of their need, chemically, to seek electrons from other atoms or ions. If a free radical particle can take an electron from another particle then that particle is left with un-paired electrons and so it becomes a free radical and so on in a chain reaction in many situations. These chemical reactions play an important role in atmospheric chemistry many other chemical processes, including human physiology.
Free radicals play an important role in the human biology such as the intracellular destruction of harmful bacteria and viruses. However, stress and environmental factors such as pollution, radiation, and cigarette smoke is known to generate free radicals. Since free radicals are necessary for life, the body has a number of mechanisms to minimize free radical damage and to repair damage which does occur. However because of their reactivity, free radicals can cause unwanted reactions as well which can result in tissue damage. Free radical damage is also cumulative so the effects increase with age.
Antioxidants are substances that can remain in a stable form even when they lose an electron from a pair - vitamins E and C are examples of antioxidants that occur naturally. The body naturally maintains a system of multiple types of antioxidants, such as vitamins C and E to help counteract harmful processes such as oxidation. Maintaining healthy levels of antioxidants by eating a well-balanced diet can help ensure your body is best able to deal with the harmful effects of free radicals.
