A compound formed by the union of two amino acids
A
Polypeptide
B
Monopeptide
C
Peptide bond
D
Dipeptide
Explanation: 

Detailed explanation-1: -A dipeptide is formed when two amino acids are joined together by a peptide bond. The peptide bond is formed via dehydration synthesis when a hydroxyl is removed from amino acid 1 and a hydrogen is removed from amino acid 2 to form water as a byproduct. The resulting C-N bond is a peptide bond.

Detailed explanation-2: -1: Amino acids undergo condensation to form a molecule called a dipeptide. The C−N bond is called a peptide bond. A peptide bond is the amide bond that occurs between the amine nitrogen of one amino acid and the carboxyl carbon of another amino acid. The resulting molecule is called a dipeptide.
