Secondary Protein Structure Quiz

The two shapes that can form within proteins due to the hydrogen bonds are the α-helix and the β-pleated sheet.

The α-helix shape occurs when the hydrogen bonds form between every fourth peptide bond, specifically between the oxygen of the carboxyl group and the hydrogen of the amine group.

The β-pleated sheet shape forms when the protein folds so that two parts of the polypeptide chain are parallel to each other, enabling hydrogen bonds to form between parallel peptide bonds.
