SYNTHON CHEMISTRY AND PREBIOTIC STAGE. FORMATION ON EARTH OF THE FIRST PROTEINOGENIC AMINO ACIDS AND THEIR POLYPEPTIDES WITH S (L) CONFIGURATION


Gheorghe SURPATEANU1

Abstract: From three synthons: methylene, nitrene and carbon monoxide in nitrogen, at low temperatures, aziridinone is formed, asymmetrically compound under certain thermodynamic conditions. From aziridinone and methylene, under the influence of polarized light, the C-methyl-aziridinonyl radical, C(S) N(R), is preferably formed. From this radical and the same three syntones, 19 proteinogenic amino acids C(S) can be formed. Glycine, the only achiral proteinogenic amino acid, would be obtained from aziridinone or C-aziridinonyl radical. Part of the proteinogenic amino acid precursors by copolymerization forms the backbone polypeptide precursors, C(S). The first C(S) polypeptides would have formed from polypeptide precursors and not from amino acids. As scientific support for the above, we mention: a) in our experiments, from methylene and a mixture of: CO2, NH3 and H2O, at low temperatures, amino acids were formed; b) compounds: CH2, NH, CO, CO2, H2O, NH3, SH2, HNCO, •CH3, •CH, •SH, •SCH3 and glycine (ice comet), involved in the formation of proteinogenic precursors, are on the list of ’’interstellar molecules” and c) our studies of thermodynamics and chemical reactivity, according to which at low temperatures, through interradical reactions, under the influence of polarized light, such asymmetric syntheses can take place.

Keywords: amino acids, polypeptides, S (L) configuration, synthons, aziridinone, precursors.
