Nonionic Amphiphilic Compounds from Lysine as Molecular Mimics of Lecithins

Article abstract of DOI:10.1007/BF02523452

New monodisperse nonionic surfactant molecules, based on lysine with two fatty acid chains in the hydrophobic part and one or two polyoxoethylene methoxycapped chains (EO_n-Me) in the hydrophilic headgroup, are synthesized as mimics of natural lecithins.Their surface-activity properties indicate that these compounds have surfactant behavior whose global hydrophobic contribution is comparable to that of one fatty chain. - Key Words: Amphiphilic compounds; critical micelle concentration; mimics of lecithins; surface tension
