The beta-sheet structure is a fundamental element of protein secondary structure characterized by beta strands linked laterally by at least two or three backbone hydrogen bonds, forming a sheet-like arrangement. This structure contributes to the stability and functionality of proteins and is crucial in the formation of protein complexes and aggregation-related diseases like Alzheimer's.

Protein secondary structure refers to the local spatial arrangement of a polypeptide's backbone atoms, primarily stabilized by hydrogen bonds. The main types are alpha helices and beta sheets, which are crucial for a protein's overall 3D conformation and function.

The stability of proteins is crucial for their biological function and is influenced by a variety of factors including temperature, pH, and the presence of stabilizing agents. Understanding protein stability is essential for applications in drug design, enzyme engineering, and the development of therapeutic proteins.

Protein complexes are assemblies of multiple protein molecules that interact to perform specific biological functions, often exhibiting properties that are not present in individual proteins. These complexes are essential for a wide range of cellular processes, including signal transduction, DNA replication, and metabolic pathways, and their formation and regulation are critical for maintaining cellular homeostasis.
