we have a chemical experiment about ninhydrin test, a color test for amino acids and short peptide chains. I want to know what chemical nature does the Nutrasweet has because our professor is asking why use nutrasweet in executing the ninhydrin test.

Aspartame is a modified dipeptide, I believe the two amino's are aspartic acid and phenylalanine, and upon hydrolysis the two amino acids can be separated, giving a positive ninhydrin test, along with a methanol group produced. There is a methyl group bound to the carboxylic acid moiety of the phenylalanine. Ask your professor if you can test for the presence of methanol.

It is not a sugar (saccharide) molecule, that is it contains no glucose whatsoever otherwise diabetics will have a problem.
It must be another type of chemical which tastes sweet, for example esters which are easily broken down into harmless products.

It activates taste buds similar to the ones sugar activates. It dissolves in water so it must have polar molecules.

Structure similar to glucose though not decomposable to energy.
