The α helix and β pleated sheet are examples of which level of protein structure?

Question

Quizplus · Accepted Answer

The α helix and β pleated sheet are both examples of secondary protein structure, which refers to the regular folding patterns of the polypeptide backbone that result from hydrogen bonding between amino acids that are nearby in sequence. The primary level refers to the linear sequence of amino acids in the protein, while tertiary structure refers to the overall 3D folding of a single polypeptide chain and quaternary structure refers to the arrangement of multiple polypeptide chains in a protein complex. Therefore, choice B is the best answer.
