What are mineral salts? Where in living beings can mineral salts are found?
Mineral salts are simple inorganic substances made of metallic chemical elements, such as iron, sodium, potassium, calcium and magnesium, or of non-metallic elements, such as chlorine and phosphorus.
They can be found in non-solubilized form, as part of structures of the organism, such as the calcium in bones. They can also be found solubilised in water, as ions: for instance, the sodium and potassium cations within cells.
