WebBeside alpha-helices, beta-sheets are the most common secondary structure elements of proteins. … Parallel beta-sheets and their subunits are energetically less stable and indeed found to occur more rarely in proteins. Antiparallel hairpins are disfavored compared to beta-sheets formed by sequentially separated strands. WebThere are two main types of secondary structures. Two fibrous structures the alpha helix, and the beta pleated sheet, which are structural components of the cell. The alpha helix is formed when the polypeptide chains twist into a spiral. This allows all amino acids in the chain to form hydrogen bonds with each other.
