In which, on the other hand, we do not want to exclude that maybe also the thermal motion is, in a way and somewhere, functionally exploited. One may also admit that the inter-molecular forces in [the cases of] amino acids and peptides are rather strong, which fact is, not in the last place, connected with the fact that, still before demonstrable compounds appear, they [i.e. the inter-molecular forces] already are almost true chemical forces.
