Influence de composés à hétérocycle azoté et particulièrement d'azoles non condensés sur des réactions «prébiotiques» de condensation d'acides α??aminés induites …
Summary In previous experiments aqueous solutions of a-aminoacids in the presence of cyclic or linear polyphosphates, pH range 7-11, yielded up to 40% of dipeptide but only 0.3- 0.5% of tripeptide [l][2]. By addition of imidazole the yield of tripeptide could be increased about ten times [2]. Therefore, we have studied for the condensation reaction of glycine the influence of the addition to aqueous solutions 0.1 M in glycine and 0.1 M in ...
