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.A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with backbone in an extended conformation.

In molecular biology the term double helix refers to the...
