How are beta pleated sheets formed
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 … WebThe beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure.Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with …
