At its core, an amphiphilic peptide is constructed by linking a hydrophilic peptide sequence to a lipid tail, which typically consists of a hydrophobic alkyl chain ranging from 10 to 16 carbons. Alternatively, an amphiphilic peptide can be made by attaching a stretch of nonpolar amino acid residues that form the hydrophobic tail to polar or charged amino acids that constitute the hydrophilic head. This strategic design imbues these molecules with the ability to interact with both aqueous and non-aqueous environments, a critical trait for their self-assembling behavior.
