Quizplus · Accepted Answer

An amphipathic helix has both hydrophobic and hydrophilic residues. The hydrophobic residues are on one side of the helix and the hydrophilic residues are on the other side. The peptide N_term-RIFHKVAE-C_term has a hydrophobic side (RIF) and a hydrophilic side (HKVAE). This peptide could form an amphipathic F1F1F1S1F1F1F10 helix.
