Reactive oxygen molecules are different than normal oxygen molecules. They have been changed by the process of oxidation and are very unstable. Because they are unstable, they tend to react with anything that they come in contact with. When in contact with cells in the body or the DNA within those cells, the reaction can be damaging and causing cell death or DNA mutation Many molecules in living things have oxygen in them, such as proteins, nucleic acids, carbohydrates and fats. Oxygen is a part of water, which all known life needs to live. Algae, cyanobacteria and plants make the Earth's oxygen gas by photosynthesis, using the Sun's light to get hydrogen from water, giving off oxygen. Oxygen gas (O 2) was isolated by Michael Sendivogius before 1604. It is.

Oxygen's high reactivity is due to its biradical electron configuration. Its two unpaired electrons make the molecule highly susceptible to bond formation. This has proven a challenge in efforts to create oxygen supplements that have the ability to go systemic, and not just die in the gut Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants, the result is an explosive release of energy and the production of water

Oxygen is neither an organic nor inorganic molecule, because by itself it is just an atom. A molecule is two or more atoms joined together. Then again, if two oxygen atoms bond, this would form an oxygen molecule, however the classification of this is a little tricky. It is definitely not organic, as this would require it to contain carbon, and. Ozone (O 3) is a triatomic molecule, consisting of three oxygen atoms.It is an allotrope of oxygen that is much less stable than the diatomic O 2 (oxygen gas)..
