Amine
Explanation
Two amino acids are linked by a peptide bond which is formed when the carboxyl group of one amino acid reacts with the amino group of the next amino acid. When a phosphate moiety links the 3′ carbon of one sugar of one nucleotide to the 5′ carbon of sugar of succeeding nucleotide, a phosphodiester bond is formed.
