As shown in the bottom of Figure , only 813 out of 10 7 samples were found to have 70-80% probabilities of finding vesicles. This low percentage can also seen in the histogram shown in Figure . The majority of samples concentrated on the probability of 0.1, which means they may not form vesicles according to the model-predicted probabilities. Interestingly, as a quaternary amine, decyl trimethylamine has the same functional group that is found in phosphatidylcholine head groups in modern lipids. Likewise, the decyl sulfate anion is an analogue for a phosphate group, giving this composition type a similar charge structure to lipid bilayers in extant cells.
