Residue Ala$-13$ has been marked in the figure below. Note that hydrogen atoms have been omitted to improve clarity by reducing the number of overlapping atoms drawn in the figure. Use your knowledge of $H-$bond donors and acceptors, and your understanding of the $H-$bonding patterns seen in alpha$-$helices to identify all of the correct statements listed below. Each correctly assigned answer earns $0\mathrm{.}1$ marks.

This helix is LEFT$-$handed.

The carbonyl oxygen in Ala$-13$ accepts an $H-$bond from the amide nitrogen in Ala$-17.$

The amide nitrogen in Ala$-13$ donates an $H-$bond to the carbonyl oxygen in Ala$17.$

The amide nitrogen in Ala$-9$ donates an $H-$bond to the carbonyl oxygen in Ala$13.$
