Solution

The correct option is A 2
Number of peptide linkages in the artificial sweetener aspartame is 2. Aspartame has the chemical formula $C_{14} H_{18} N_{2} O_{5}$ . Aspartame is the methyl ester of the dipeptide of the natural amino acids, $L$ -aspartic acids and $L$ -phenylalanine. It is composed only of the $L$ -isomers. It is odorless and dissolves in water. Under strongly acidic conditions, the peptide bonds are also hydrolyzed, resulting in the free amino acids. It is a nonpolar molecule.
