Deuterium
In nature hydrogen exists in three varieties: hydrogen (H) with a mass number of one, deuterium (D) with a mass number of two and tritium (T) with a mass number of three. D is a stable and non-radiating isotope of hydrogen. It has been well-known for decades that due to their mass difference, H and D behave differently in chemical reactions. In other words, D can be considered as an independent element. When D was applied in great concentrations, D exerted a major impact on various biological systems (viruses, algae, plants, mice, etc.) which is the consequence of the so called isotopic effect.
In view of the water content of living organisms and the D2O concentration of natural waters (0.015 atom%) the D concentration in the living organisms is more than 10 mM/L. Just to put this figure in perspective it should be noted that the Ca2+ concentration in human blood is approx. 2 mM/L. It means that up to now modern science ignored an element, which is present in five times higher concentration than calcium.
