Which bonds join adjacent amino acids in a polypeptide?
A.Peptide bonds
B.Hydrogen bonds
C.Glycosidic bonds
D.Phosphodiester bonds
Explanation
Core Concept
A peptide bond is the covalent linkage between the carboxyl carbon of one amino acid residue and the amino nitrogen of the next. Repeated peptide bonds form the polypeptide backbone. In ribosomal translation, peptide-bond formation occurs through transfer of the growing peptide from tRNA to the incoming aminoacyl-tRNA, so it should not be described as simple dehydration between two free amino acids.
