WebbBeta sheets are stabilized by hydrophobic contacts and backbone hydrogen bonding. Alpha helices are largely stabilized by backbone hydrogen bonding. That is, local interactions … WebbA) An α helix repeats after 18 residues and has 3.6 residues per turn. B) A network of main-chain hydrogen bonds connect β strands in a β sheet. C) The most common structures are the α helix and the β sheet. D) The 310 helix is right … beading saw

WebbThe 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 … WebbAlpha helix sheets are less durable than beta pleated sheets, but they are more comfortable to wear. The pleats on beta pleated sheets provide more space between the … Webb17 juli 2024 · The secondary structure describes the three-dimensional folding or coiling of a chain of amino acids (e.g., beta-pleated sheet, alpha helix). This three-dimensional shape is held in place by hydrogen bonds. A hydrogen bond is a dipole-dipole interaction between a hydrogen atom and an electronegative atom, such as nitrogen or oxygen. dg stock price zacks
