Question

Which of the statements about peptide bonds are true? Peptide bond formation is a hydrolysis reaction. A tetrapeptide contains five amino acid residues. Peptides are polymers of amino acids. Peptide bonds are ester linkages. Peptide bonds form from nucleophilic attack by an electron pair on an ?-amino nitrogen atom on an ?-carboxyl carbon atom of another amino acid.

Which of the statements about peptide bonds are true? Peptide bond formation is a hydrolysis reaction. A tetrapeptide contains five amino acid residues. Peptides are polymers of amino acids. Peptide bonds are ester linkages. Peptide bonds form from nucleophilic attack by an electron pair on an α-amino nitrogen atom on an α-carboxyl carbon atom of another amino acid.
