Selenium (Se) is an essential trace mineral required for growth, development, immune function, and metabolism. Selenium exerts its biological effects as an integral component of selenoproteins (SePs). Deficiency or low Se status leads to marked changes in many biochemical pathways and a range of pathologies and disorders which are associated with SeP function.

Selenium - ScienceDirect

1. Introduction. Selenium (Se) was discovered by the Swedish chemist Berzelius in 1817 and is named after Selene, the Greek goddess of the moon. In 1957, Se was first identified as an essential trace element in mammals (Schwarz and Foltz, 1957), and is now known to be required for a variety of functional Se-dependent proteins (selenoproteins) in most living organisms (Mayland, 1994, Hesketh ...
