The alpha helix and beta pleated sheet represent which level of protein structure?

Polypeptide chains represent the primarylevel of protein structure. The secondarystructure of a protein results from hydrogen bonding between amino acids in the peptide chain. This leads to twisting or folding of the chain into the alpha helix and the beta pleated sheet shapes.
