Amphiphilic
Amphiphilic — Describing a molecule with both hydrophilic and hydrophobic regions, a property exploited in the design of cell-penetrating and antimicrobial peptides.
What Does Amphiphilic Mean?
Amphiphilic describes molecules possessing both hydrophilic (water-loving) and hydrophobic (water-repelling) regions. In peptide science, amphiphilic peptides spontaneously organize at interfaces and self-assemble into nanostructures in aqueous solution. The term is closely related to amphipathic but is used more broadly to include non-peptide molecules.
Applications
- Peptide amphiphiles: Alkyl tail + peptide headgroup creates self-assembling nanofibers
- Surfactant peptides: Short amphiphilic peptides (A6D, V6D) form vesicles and nanotubes
- Membrane interaction: Amphiphilic CPPs and AMPs insert into lipid bilayers via their hydrophobic face
