Like a helices, B sheets often have one side facing the surface of the protein and one side facing the interior, giving rise to an amphiphilic sheet with one hydrophobic surface and one hydrophilic surface. From the sequences listed below, pick the one that could form a strand in an amphiphilic ß sheet. O TLNISFQMELDV DSETKNAVFLIL VLEFMDIASVLD
