Summary
The purine nucleosides (adenosine, guanosine, inosine, xanthosine) are formed when the corresponding purine bases and D-ribose are heated together in the presence of certain salts and minerals. The salts remaining after the evaporation of seawater are particularly effective in these syntheses. The relevance of these reactions for prebiological evolution is discussed.
