The second common secondary structure is the beta pleated sheet, which consists of two or more beta strands. The backbone of a Apa perbedaan antara Alpha Helix dan Beta Pleated Sheet? Struktur Helix Alpha dan Beta Pleated Alpha Helix: Pada struktur ini, tulang punggung polipeptida terikat erat di sekitar sumbu imajiner sebagai struktur spiral. Hal ini juga dikenal sebagai susunan helicoidal rantai peptida. Abstract. Alpha-helices and beta-sheets are the two most common secondary structure motifs in proteins.

Alpha helices and beta sheets are supported and reinforced by hydrogen bonds. A hydrogen bond is a weak bond formed when a hydrogen atom is covalently bonded to an atom and interacts with another atom.
