Periodic table of elements and their nucleosynthesis. Biological utilisation of the elements and biometals (in orange and yellow) and their nucleosynthesis processes in the Universe are indicated. CHNOPS elements and elements used as electron donors/acceptors by biology are also reported. Iron and Manganese are the only biometals that not only serve as cofactors, but might also be used as metabolic substrates for redox reactions. -- astro-ph.EP

Transition Metal Abundance As A Key Parameter For The Search Of Life In The Universe

by Keith CowingSeptember 28, 2025September 28, 2025

The search for Life in the Universe generally assumes three basic life’s needs: I) building block elements (i.e., CHNOPS), II) a solvent to life’s reactions (generally, liquid water) and III) […]
