Aspartame is an artificial sweetener that has the structure shown below. aspartame OH O O O NH2 H3C N H O Draw a circle around each chiral centre in aspartame. In the stomach, aspartame is hydrolysed by acid to form three organic products. On the diagram above, use arrows to indicate the two bonds that would be hydrolysed in the stomach. Draw the structures of the three products formed after complete acid hydrolysis of aspartame. Aspartame is soluble in water. By referring to the structure of aspartame, explain why it is soluble in water. Recently, nanotechnology has been involved in the development of a new natural sweetener, Nano Sugar, extracted from sugar cane. What is the approximate width of a nanoparticle?
