Beta pleated sheets are vital to protein stability and function, featuring in structures like silk fibroin. These sheets, stabilized by hydrogen bonds, can be parallel or antiparallel, with the latter providing exceptional stability. Understanding their formation and role is key to advancements in protein engineering and material science.
