D)Quaternary

Question

Quizplus · Accepted Answer

α-helices are a secondary structure of proteins, which refers to the local folding of the polypeptide chain into patterns such as α-helices and β-sheets, stabilized by hydrogen bonding between neighboring amino acids. The primary structure refers to the linear sequence of amino acids, while the tertiary structure describes the overall 3-dimensional shape of a single polypeptide chain, and the quaternary structure refers to the arrangement of multiple polypeptide chains in a protein complex.
