15.6 Amino acids are joined together by peptide bonds. In a peptide bond, the carboxyl group of one amino acid is covalently attached to the amino group of another amino acid.

The primary structure of a protein is its sequence of amino acids.

Interactions between amino acids cause the primary structure to fold into a secondary structure, such as this alpha helix.
