A well-known artificial anti-oxidant, TEMPO, is up to 100 times more powerful than nature's best, and could help counteract everything from skin damage to Alzheimer's disease, a study has found.
Free radicals are highly reactive molecules that are naturally present in the body and are created during routine natural processes like breathing, according to researchers at the University of British Columbia in Canada.
"Free radicals are a natural part of human metabolism. But when our bodies have too many, like when we are exposed to UV radiation from the Sun, when we smoke, or even when we drink alcohol, it can be a problem," said Gino DiLabio, a professor at UBC.
"These extremely reactive molecules can damage cells or DNA and can contribute to many different diseases, like Alzheimer's, and some researchers think they may even be responsible for aging," DiLabio said. -- PTI
