Question

What is the amide bond that occurs between the amino nitrogen of one amino acid and the carboxyl carbon of another amino acid?

Answer 1

a peptide bond

A peptide bond is the amide bond that occurs between the amino nitrogen of one amino acid and the carboxyl carbon of another amino acid. The resulting molecule is called a dipeptide. Notice that the particular side chains of each amino acid are irrelevant since the R groups are not involved in the peptide bond.
