41,500 ppm and 20 ppm. Concentrations of calcium and lithium in Earth’s crust. 18 million metric tons. Calcium reserves in the US. 40.078 u and 7.016 u ...

Their study reveals that calcium ions help determine the molecular "handedness" (chirality) of tartaric acid polymers—an essential feature of biological molecules like DNA and proteins.

Calcium-poor settings, such as some lakes or ponds, may have promoted homochiral polymers, while calcium-rich environments might have favoured mixed-chirality polymers. Beyond chemistry, this research ...
