Thermal Synthesis of Amino Acids from Acetonitrile - Water Vapor in Presence and Absence of Metal Oxides (Silica and Alumina) Under Prebiotic Wetting and Drying Conditions of Primitive Earth

The chemical events that took place about 4.5 to 3.5 billion years ago on the primitive era of our planet leading to the origin of first speck of life from fundamental abiogenically formed biomultimolecular compounds have always attracted the attention of scientists since time immemorial. Synthesis of amino acids from reaction system of acetonitrile water vapor have been carried out under prebiotic wetting and drying conditions of primitive earth in presence and absence of metal oxides and significant results have been obtained. The resulting products have been identified by paper chromatography, high performance liquid chromatography as well as by ultraviolet spectroscopy. Formation of lysine, aspartic acid, serine, glycine, glutamic acid, valine, leucine and α-alanine have been reported from aqueous solution of acetonitrile heated with silica and alumina as sensitizers under wetting and drying conditions of primitive earth.
