Condensation Reactions of Amino Acids under Hydrothermal Conditions with Adiabatic Expansion Cooling

概要
- 論文の詳細を見る
A novel flow reactor adopted for the adiabatic expansion cooling method, a rapid quenching method, was designed to synthesize oligopeptides from amino acids under hydrothermal conditions. We studied the hydrothermal reaction under the two experimental conditions, whose raw materials were glycine and diglycine aqueous solution. The temperature, the pressure and the residence time of the reaction were 270°C, 10 MPa and 27 seconds, respectively. Then we could obtain long oligoglycines like octa-, nona- and decaglycine. The concentration profiles of each product in the two experimental conditions were similar. It suggests that the equilibrium relations would be established between condensation reactions and hydrolysis reactions of oligoglycines, which might light up a new pathway to the study of the origin of life.
