The Sikhote-Alin (SA) meteorite is an example of a type IIAB octahedrite iron meteorite with ca. 0.5 wt% phosphorus (P) content principally in the form of the siderophilic mineral schreibersite (Fe,Ni)(3)P. Meteoritic in-fall to the early Earth would

'How did life on Earth originate?' is a question that, as yet, scientists have been unable to answer. From simple building blocks, under certain conditions, a series of chemical reactions occurred leading to the formation of a living cell. Meteorites

Phosphorus is presumed to have been a limiting nutrient in the Archean ocean due to binding to iron oxides. Here, the authors show the heating of iron with phosphate results in the reduction of phosphate to the ion phosphite, which is solubilized and

The emergence of mechanisms for phosphorylating organic and inorganic molecules is a key step en route to the earliest living systems. At the heart of all contemporary biochemical systems reside reactive phosphorus (P) molecules (such as adenosine tr

Metabolism is primed through the formation of thioesters via acetyl CoA and the phosphorylation of substrates by ATP. Prebiotic equivalents such as methyl thioacetate and acetyl phosphate have been proposed to catalyse analogous reactions at the orig

Phosphorus is an element critical to the formation of several biomolecules, including nucleic acids, the energy transfer molecule ATP, and phospholipids. It hence lies at the heart of several biomolecular functions. However, the formation of these ke
