WebTertiary structure results from interactions between side chains, or between side chains and the polypeptide backbone, which are often distant in sequence. Every protein has a particular pattern of folding and these can … WebTertiary Structure and Beyond Historically, the first hierarchical description of protein structure contained two more levels, in addition to primary and secondary (Linderström-Lang and Schellman, 1959). Tertiary structure concerns how the secondary structure units associate within a single polypeptide chain to give a three-dimensional structure.
