“…However, decanoic acid vesicles have their own limitations. Decanoic acid vesicles can be formed only above the melting point of the acid about 32 • C, though stable in the solid phase down to 23 • C (Apel, 2003), and in the extremely low concentration of divalent ions or in their total absence (Monnard et al, 2002). Enhancement of oligomerization of monomers encapsulated inside decanoic acid vesicles could have been likely only when the temperature of the cold regions surrounding hydrothermal vents in the ocean was above 32 • C and well before the concentration of metallic ions or ionic strengths in the surrounding seawater became high enough.…”

We compared three different kinds of lipid vesicles made of saturated fatty acids, unsaturated fatty acids, and phospholipids for their evolutionary capabilities in a simulated hydrothermal environment. Encapsulation of the glycine monomers enhanced the oligomerization of peptides in all cases. Fatty acid vesicles remained stable at higher temperatures and efficiently utilized heat energy for this synthetic reaction. Phospholipid vesicles were destabilized by higher temperatures, and thus were found to be better suited to enhance synthetic reactions at lower temperatures.
