The ________ structure of a protein refers to how chains of amino acids coil to form characteristic patterns such as the alpha-helix.
A)primary
B)secondary
C)tertiary
D)quaternary

Question

Quizplus · Accepted Answer

The secondary structure of a protein is the pattern of folding that results from hydrogen bonding between the backbone atoms (not the side chains) of amino acids. This includes alpha-helices, beta-sheets, and random coils. The primary structure refers to the linear sequence of amino acids, the tertiary structure refers to the overall 3D shape of a single protein molecule, and the quaternary structure refers to the spatial arrangement of multiple protein molecules in a complex.
