Oxygen radicals occur as a by-product when living beings burn carbohydrates or fat. They are suspected of accelerating the aging process in humans and animals, and to be partly responsible for severe ...

For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules ...

During evolution, one of the main developments of organisms was the ability to extract oxygen from the environment and carry it to each cell in multicellular organisms in time through metabolism. Life ...

Free radicals are a hot topic in wellness, but because of their ominous name – “radical” certainly sounds alarming – a lot of people misunderstand them, their complex role in our bodies and how to ...
