The prestigious American magazine "Proceedings of the National Academy of Sciences of the United States of America" this week published an article by a research group at the University of Delaware, led by biochemist Sharon Rozovsky, which examined the selenium-containing proteins and their antioxidant role in human health.
The international team of researchers started from the assumption that Selenium has long been studied for its role in aging, cancer and chronic diseases. In particular, the proteins, called selenoproteins, which incorporate selenium through an amino acid, are essential for mammals and play important roles in antioxidant defense.
These proteins play an essential role in the chemical reactions known as redox reactions, which consist of reduction (loss of oxygen) and oxidation (gain of oxygen).
Rozovsky and his team have used mass spectrometry and nuclear magnetic resonance spectroscopy to study the effects of selenium, deepening scientific understanding of the chemical involved. "There are thousands of proteins in the human body, and only 25 contain selenium., It is important for cancer prevention and longevity, so we want to understand exactly how it works. When the cells produce energy through the normal process, they produce oxygen , which in the long term can damage the cells themselves. Such damage accumulates over the years, and can lead to serious diseases such as cancer and Alzheimer's.
