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. WebWhen a single polypeptide chain folds onto itself to form beta-sheets between its segments, the folding is done by beta-bends. These bends connect the two antiparallel sheets. Beta-bends mostly include charged residues.
