Abstract

Bringing phosphorus to life: The prebiotic origin of key biomolecules such as RNA and ATP is contingent on a source of condensed phosphates, such as pyrophosphate and triphosphate. Condensed phosphates can be produced at high yields from the oxidation of H-phosphonate or H-phosphinate. Reactive phosphates were likely abundant on the early earth's surface, setting the stage for prebiotic chemistry that led to the evolution of life.
