Characterization of Ionizable Groups in Thermally Prepared Polyamino Acids

  • Etsuo Kokufuta

In an attempt to clarify the process of evolution of small molecules to macromolecules under prebiotic conditions, attention should be paid to the formation of polymers of amino acids. Only the thermal method successfully yields polyamino acids under simulated geological conditions (e.g., Fox and Dose, 1977). The thermally prepared polyamino acids possess some proteinlike properties; therefore, they have drawn attention as possible abiotic proteins (Fox, 1965).
