Select the correct statements about aspartame.

  1. AIt contains two amide linkages.
  2. BIt contains one ester group.
  3. CIt contains a free carboxylic acid group.
  4. DIt contains a benzene ring.

Answer: B, C, D

Aspartame is the methyl ester of aspartyl-phenylalanine: it has one amide bond, one ester (the methyl ester), a free carboxylic acid on the aspartic acid side chain and the benzene ring of phenylalanine. Statement 1 is false because there is only one amide linkage in a dipeptide.
