Minerals
Some elements need to be present in the diet in relative large amounts. They are
usually called macrominerals or "bulk minerals". Some are structural, and some play
a role as electrolytes.
Many elements are termed trace minerals. They are only needed in trace amounts, usually
because they play a catalytic role in various enzymatic processes.
You can find more about each of the minerals by following the links below.
Some minerals are present in extremely small amounts (less than 0.0001% by weight)
in biological tissues. Nevertheless they may still have a role to play. They are
called ultratrace elements including boron (B), bromine (Br), cadmium (Cd), fluorine
(F), lead (Pb), lithium (L), nickel (Ni), silicon (Si), tin (Sn), and vanadium (V).
