Question

Which of the following alternative (artificial) sweeteners is made up of two amino acids, aspartate, and phenylalanine? As a result, people with phenylketonuria (PKU), who cannot metabolize phenylalanine, need to be aware of which products contain this sweetener?

A. Saccharin

B. Sucralose

C. Aspartame

D. Acesulfame potassium

Answer 1

Aspartame is the sweetener made of amino acids aspartate and phenylalanine, and it is specifically important for individuals with PKU to avoid it.

Step-by-step explanation:

The artificial sweetener made up of two amino acids, aspartate and phenylalanine, is Aspartame. Aspartame is a methyl ester of a dipeptide composed of these amino acids and is about 180 times sweeter than table sugar.

Individuals with phenylketonuria (PKU) a genetic disorder where the enzyme to metabolize phenylalanine is missing must avoid aspartame since it releases phenylalanine upon digestion which can build up and cause brain damage. All products containing aspartame must carry a warning label to inform consumers, especially those with PKU.
