Draw the structures of the following compounds and use dashed lines to indicate where they form hydrogen bonds to other molecules of the same kind: (ii) methyl formate

Consider the following unnatural amino acid:

c. Draw the cyclic ester resulting from the intramolecular reaction of the hydroxyl group of this amino acid with its carboxyl group (cyclic esters are called lactones).
