Abstract
Vacuum ultraviolet (VUV) radiation, a powerful energy source in free Space, have been established to promote synthesis of natural nucleotides. It is shown that lunar ground protects from destruction (up to 1.5–2.0% ) the nucleotides formed after VUV-irradiation of dry films (adenosine and inorganic phosphate). Identification and quantitative determination of the products of synthesis and destruction is performed by the method of high performance liquid chromatography. The following products of synthesis are found: 5'-AMP > 2'3'-cAMP > 2'-AMP > 3'5'-cAMP > 3'-AMP. The obtained results are discussed from the viewpoint of hypothesis about the Space (extraterrestrial) origin of biologically important compounds that were initial for evolution on the Earth.
