Explanation:

Protein secondary structure refers to the regular, repeating patterns of folding of the polypeptide backbone due to hydrogen - bonding. The overall three - dimensional shape of a single polypeptide chain is tertiary structure. Interactions between two or more polypeptide chains is quaternary structure. The sequence of amino acids in a polypeptide is primary structure.

Answer:

The repeating pattern of folding between regions
