Beta-Pleated Sheet
Definition
A beta-pleated sheet is another form of secondary structure in proteins where parts of the polypeptide chain fold back on themselves to form "sheets," also held together by hydrogen bonds.
Analogy
Imagine folding paper accordion-style; this zig-zag pattern resembles how polypeptides fold to create beta-pleated sheets.
