摘要：

The ability of montmorillonite clay minerals for catalyzing peptide formation from amino acids in aqueous solution has been investigated using glycine and Cu2+ and Ca2+ containing montmorillonites as reaction systems. Evaporation cycle experiments showed that minor amounts of di- and tripeptide are formed from the amino acid. Further polymerization of dipeptide, however, seems to be more favoured by this reaction system than the initial step of dipeptide formation, and a possible role of clays in prebiotic peptide evolution could be seen therefore in the prolongation of peptide chains. Cu2+ ions in the clay matrix did not show any advantage over the usual Ca2+ ions embedded in natural montmorillonite.
