One of the predominant secondary structure features of proteins, sheets (beta sheets) are formed by the juxtaposition of sections of polypeptide chains in relatively extended conformations known as -strands. They are often flanked by irregular loop structures and are less well conserved, than beta-sheet forming beta-strands, among homologous protein structures.
Concept #2: Antiparallel and Parallel Beta Sheet Hydrogen Bonding. Concept #1: Beta Strand vs. Alpha Helix. -Helices become more stable as they grow longer. Alpha helices are largely stabilized by backbone hydrogen bonding.
Beta pleated sheet or beta sheet is a common secondary structure of proteins. The green lines represent hydrogen bonds between the strands. Report issue. beta sheet. The obtained propensities for -helices are consistent with each other, and the pair-wise correlation coefficient is frequently high. The . Uncategorized beta strand vs beta sheet.
