O knihe
In the first part of this book, there are presented five main stages involved in the appearance and evolution of life on Earth: a)-inorganic matter, b)-organic matter, c)-prebiotic matter, d)-emergence of first forms of life and e)-from unicelular organisms to multicelular organisms. The main part of this book is dedicated to prebiotic stage concretely, to synthone chemistry. The formation of the first proteinogenic aminoacids S(L) and corresponding polipeptides with back-bone S(L) on the Earth are explained for the first time. The first polipeptides were formed from polipeptide precursors and not from the proteinogenic aminoacids. Experimental data concerning the behaviour of synthones (methylenes, nitrenes, carbon monoxide) in the presence of primary atmosphere components could explain the formation of the first aminoacids. Also, theoretical studies of chemical reactivity using D Gauss B88-LYP, CGA functional with DZVP basis sets, are presented in this book.
