Beta sheet - Wikipedia
The beta sheet (β-sheet, also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.
Secondary Structure: β-Pleated Sheet - Chemistry LibreTexts
This structure occurs when two (or more, e.g. ψ-loop) segments of a polypeptide chain overlap one another and form a row of hydrogen bonds with each other.

beta strands (sheets) in which the hydrogen bonds are between backbone atoms (again amide Hs and carbonyl Os) on noncontinuous stretches of the protein, and reverse turns, which occur within a very short continuous stretch of amino acids.
Beta Sheet - an overview | ScienceDirect Topics
A beta sheet consists of two or more beta strands linked by hydrogen bonds. Adjacent strands that form the beta sheet can either run in opposite directions (antiparallel beta sheet) or in the same direction (parallel beta sheet).
Alpha-Helix and Beta-Sheet - Introduction, Types and Differences ...
Alpha-Helix and Beta-Pleated sheets are types of the secondary structure of the protein. They both are shaped by hydrogen bonding between the carbonyl O of one amino acid and the amino H of another.
Secondary Structure (2˚) -- Beta Strands - University of Vermont
A beta strand is an element of secondary structure in which the protein chain is nearly linear. Adjacent beta strands can hydrogen bond to form a beta sheet (also referred to as a beta pleated sheet).
4.3: Secondary Structure - Biology LibreTexts
Aug 23, 2021 · About 50% of the amino acids in a globular protein are in regular secondary structure (alpha or beta). The remaining amino acids are not less ordered, just less regular. An additional example of secondary structures is reverse turns (or beta-bends or beta turns).
7.4: Secondary structure of proteins - Chemistry LibreTexts
Sep 21, 2023 · Define the secondary structure of proteins and understand the structural features of major secondary structures, including \(\alpha\)-helix, \(\beta\)-pleated sheet, random coil, and triple helix structures.
Protein Secondary Structure, Alpha Helices, Beta Sheets, …
The second major secondary structure element in proteins is the β-sheet. β-sheets consist of several β-strands, stretched segments of the polypeptide chain kept together by a network of hydrogen bonds between adjacent strands.
Like the α-helix, beta-pleated sheet (β-sheet ) structures are a common feature of protein three-dimensional conformations and, again by analogy, the prevalence of β-beta sheets is most likely attributed to the inherent stability of these structures.
