Iron-Mediated Peptide Formation in Water and Liquid Sulfur Dioxide under Prebiotically Plausible Conditions

[摘要] Mediated by iron: Prebiotically plausible iron-mediated peptide coupling in water and liquid sulfur dioxide forms oligomers. The presented synthetic pathway which incorporates all proteinogenic amino acids into peptides is compatible with a wide range of prebiotically plausible scenarios as a result of the high iron abundance on (early) Earth.
