In biochemistry, an ultratrace element is a chemical element that normally comprises less than one microgram per gram of a given organism (i.e. less than 0.0001% by weight), but which plays a significant role in its metabolism. Possible ultratrace elements in humans include boron, silicon, nickel, vanadium [1] and cobalt. [2]
