Evolution of metal ions in biological systems
Evolution of Metal Ions in Biological Systems refers to the incorporation of metallic ions into living organisms and how it has changed over time. Metal ions have been associated with biological systems for billions of years, but only in the last century have scientists began to truly appreciate the scale of their influence. Major (iron, manganese, magnesium and zinc) and minor (copper, cobalt, nickel, molybdenum, tungsten) metal ions have symbiotically aligned with living organisms and the associated complexes have evolved over time.
