Phosphorylation of the nucleosides adenosine and uridine by the simple mixing and mild heating of aqueous solutions of the organic compounds with synthetic analogs of the meteoritic mineral schreibersite, (Fe,Ni)3P under slightly basic conditions (pH ~9) is reported. These results suggest a potential role for meteoritic phosphorus in the origin and development of early life.

据报道，在弱碱性条件（pH约为9）下，通过将有机化合物的水溶液与陨石矿物磷铁镍矿（(Fe,Ni)3P）的合成类似物简单混合并温和加热，可实现核苷腺苷和尿苷的磷酸化。这些结果表明陨石磷在早期生命的起源和发展中可能发挥了作用。
