Chemical structures of artificially synthesized amphiphilic compounds. TMA-C2-Glu-C12 is represented by a structure made up of a head region consisting of trimethylamine (TMA) and a hydrophobic chain comprising 2 carbon atoms (C2), a connector region consisting of glutamic acid (Glu), and 2 tail regions consisting of a hydrophobic chain comprising 12 carbon atoms (C12).
