The individual polypeptide chains in a multi-subunit protein each have their own primary, secondary, and tertiary structure.

Question

Quizplus · Accepted Answer

Each polypeptide chain in a multi-subunit protein has its own unique sequence of amino acids (primary structure), which determines its folding into alpha helices, beta sheets, and other secondary structures. The interactions between the amino acid side chains also determine its unique 3-dimensional shape (tertiary structure).
