  2. Peptide amphiphile - Wikipedia

    en.wikipedia.org/wiki/Peptide_amphiphile

    The level of amphiphilicity can vary significantly in peptides and proteins; as such they can display regions that are either hydrophobic or hydrophilic in nature. An example of this is the cylindrical structure of an α-helix , as it could contain a section of hydrophobic residues along one face of the cylinder and a hydrophilic section of ...
