Question

Quizplus · Accepted Answer

Amino acids are primarily linked in a protein by peptide bonds formed between the amino group of one amino acid and the carboxyl group of another amino acid. This type of covalent bond forms the backbone of the protein chain. Hydrogen bonds, ester bonds, and ionic bonds may also play a role in stabilizing the structure of the protein, but they are not the primary means of linking amino acids together.
