Web27 Jan 2024 · The three important secondary structures are α-helix, β-sheets, and β-turns. Also, the beta sheets can be parallel, antiparallel, or mixed. Antiparallel beta sheets are more stable because the hydrogen bonds are at a ninety degree angles. The a-helix is a coiled structure stabilized by intrachain hydrogen bonds.

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).
