The influence of ‘environmental' factors (temperature, concentration, atmosphere) are discussed. Numerous other metal ions have been investigated with respect to similar catalytic effects, and molybdenum results as the only one inducing peptide condensation, although to a much lesser extent. Experiments based on evaporation of water and redissolution lead to peptide condensation up to (gly)6 in concentrated solutions and produces peptides even starting from initially low concentrations.
