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.
WebMatt B. You are forming a carbon ring, and a 6-membered ring has the most stable bond angle, which is why you have C1-C2-C3-C4-C5-O as your ring structure. Btw, 5 membered rings also occur naturally (see: ribose) but they are simply not as stable.
