Potassium Ions are More Effective than Sodium Ions in Salt Induced Peptide Formation

摘要: Prebiotic peptide formation under aqueous conditions in the presence of metal ions is one plausible triggers emergence life. The salt-induced reaction has been suggested as being prebiotically relevant and was examined for peptides NaCl solutions. In previous work we have argued that first protocell could emerged KCl solution. Using HPLC-MS/MS analysis, found K+ more than an order magnitude effective L-glutamic acid oligomerization with 1,1'-carbonyldiimidazole solutions same concentration Na+, which consistent diffusion theory calculations. We anticipate prebiotic formed driving force, not commonly believed.
