It is often the case that a helices are positioned in a protein such that one side faces the interior of the protein and the other, the surface of the protein. These are
said to be amphiphilic helices because they face different environments. Using a helical wheel projection (shown below), which of the peptide(s) below might form
an amphiphilic helix?

A helical wheel is a two-dimensional representation of a helix, a view along its central axis.
Label the blanks on the helical wheel diagram to show the distribution of amino acid residues in a helical segment with
the sequence
-Val-Asp-Arg-Val-Phe-Ser-Asn-Val-Cys-Thr-His-Leu-Lys–Thr-Leu-Gln-Asp-Lys-
