Beta-Strand
A b-strand is one of the two regular types of secondary structure (the other being the a-helix) that is commonly observed in protein structures. The b-strand is characterized by an extended backbone conformation. The b-strand is not stable as a discrete structural unit by itself, but is stable only when it associates through hydrogen bond interactions with adjacent b-strands to form a b-sheet.
