Aspartame is a popular sugar substitute. It is 150 times sweeter than sucrose so very little is needed to sweeten foods. Identify the chirality center (s), sometimes called chiral carbon atoms, in the aspartame molecule. Indicate a chirality center by adding an asterisk (*) next to the chiral atom.
