Quizplus · Accepted Answer

Both α-helix and β-pleated sheet are types of secondary structure that are commonly found in proteins. The α-helix is a spiral-shaped structure held together by hydrogen bonds between amino acid residues, while the β-pleated sheet is a parallel or anti-parallel arrangement of β-strands that form hydrogen bonds with neighboring strands.
