Forms of Selenium

  • Raymond J. Shamberger
Part of the Biochemistry of the Elements book series (BOTE, volume 2)


The forms of selenium that occur in living systems (Table 1-1) and the forms that are biologically available to the organism depend on the form of selenium supplied to the organism, the amount of selenium supplied, and the species of plant or animal. For the purpose of this chapter it is most convenient to distinguish the forms of selenium which are present naturally. These include compounds of low molecular weight, which occur in the free form, and also natural forms of selenium which are present in high-molecular-weight compounds. Forms which are synthesized and have biological activity are listed in Chapter 9.
