Definition

A beta strand describes a single length of polypeptide chain that forms part of a beta sheet. A single continuous stretch of amino acids adopting an extended conformation of hydrogen bonds between the N-O and the C=O of another part of the peptide. This forms a secondary protein structure in which two or more extended polypeptide regions are hydrogen-bonded to one another in a planar array.
