Nature Structural & Molecular Biology - Structure of the calcium-rich signature domain of human thrombospondin-2 Skip to main content Thank you for visiting nature.com.

Even the well-known can sometimes surprise. Calcium carbonate (CaCO 3), also known colloquially as lime or chalk, is a mineral that has already been thoroughly analysed by chemists.But chemistry books ...

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 ...

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.

A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo has uncovered a surprising role for calcium in shaping life’s earliest molecular structures.
