OXYGEN RADICALS Meaning and
Definition
-
Oxygen radicals are highly reactive molecules that contain oxygen atoms with unpaired valence electrons. These oxygen atoms are known as free radicals, which means they have an unpaired electron in their outermost shell. Free radicals are unstable and seek to form chemical bonds with other molecules in order to attain stability.
Oxygen radicals can be formed in various ways, including the normal metabolic processes of the human body, as well as through exposure to environmental factors such as pollution, smoking, radiation, and certain chemicals. Once formed, these radicals can have damaging effects on cells and tissues.
When oxygen radicals react with other molecules in the body, they can cause oxidative stress, which is an imbalance between the production of free radicals and the body's ability to neutralize them with antioxidants. This oxidative stress can lead to damage to proteins, lipids, and DNA, and has been implicated in various diseases such as cancer, cardiovascular diseases, neurodegenerative disorders, and aging.
Despite their damaging effects, oxygen radicals also play important roles in physiological processes, including cellular signaling and defense against pathogens. They are involved in cell signaling pathways, immune responses, and the regulation of gene expression.
Therefore, while oxygen radicals can be harmful when present in excess, they also have essential functions in the human body. Maintaining an appropriate balance between the production and neutralization of oxygen radicals is crucial for overall health and well-being.

Etymology of OXYGEN RADICALS
The term "oxygen radicals" has a straightforward etymology. It is a combination of two words: "oxygen" and "radicals".
The word "oxygen" traces its origin back to the Greek word "oxygénēs", which means "acid-forming" or "acid-producing". This is composed of the elements "oxy-" meaning "sharp" or "acid", and "-génēs" meaning "producing" or "born of".
The term "radicals" comes from the Latin word "radix", meaning "root". In chemistry, a radical refers to a molecular species that contains one or more unpaired electrons, making it highly reactive.
Thus, "oxygen radicals" refers to highly reactive molecular species involving oxygen atoms that possess unpaired electrons.
