Webβ-Sheets are formed when several β-strands self-assemble, and are stabilized by interstrand hydrogen bonding, leading to the formation of extended amphipathic sheets in which hydrophobic side-chains point in one direction and polar side-chains in the other (Fig. 3.1D,E). What is the difference between β strands and loops? They both are degenerate. WebBeside alpha-helices, beta-sheets are the most common secondary structure elements of proteins. In this article, the question of structure and stability of parallel and antiparallel sheets of various lengths is addressed. All data obtained are compared to a selected set of protein structures.
