Vedclass · Answer

(C) Aspartame is the methyl ester of the dipeptide formed from aspartic acid and phenylalanine. In an aqueous solution,the methyl ester group $(-COOCH_3)$ is susceptible to hydrolysis. Upon standing in an aqueous medium,the ester group undergoes hydrolysis to form a carboxylic acid group $(-COOH)$,while the peptide bond remains intact under these conditions. Therefore,the structure changes to the corresponding dipeptide,which is $L-aspartyl-L-phenylalanine$.

The synthetic sweetener aspartame,known commercially as NutraSweet,is a methyl ester of a dipeptide. In aqueous solution on standing,it changes to:
