What are the functional groups in the aspartme molecule, and would aspartme be soluble in water?

Question

Aspartme has been used as an artificla sweetner.Identify the functional groups in the aspartme molecule shown. Predict, giving reasons whether or not the substance is soluble in water and other fatty tissues in our body.

Answer 1

In the question, there was no aspartame molecule shown. The functional groups are -COOH and -NH2 from the aspartic acid component of it. The substance is soluble in water, because if it were not, companies would not use it. It does not matter whether the substance is soluble in body tissues, because it is broken down, as are all proteins and peptides into its own amino acids.
