Te przeciwutleniacze Mechanism of Selenium

Selenium does not act an antioksydant on its own. Semeniud, it functions as a key contrigent of several selenoproteins that catalyze thee reduction of reactive oxygen species (ROS). Thee most well-criterized of these are the glutathione peroxidase (GPX) family, along with thioredoxin reductases and selenoprotein P. These enzymes rely on thee of seleniumem in thee form of thee acid selenocystee, which inthes intend inte.
