The major reason that antiparallel β-stranded protein structures are more stable than parallel β-stranded structures is that the parallel strands do not have as many disulfide crosslinks between adjacent strands, have weaker hydrogen bonds laterally between adjacent strands, and have fewer lateral hydrogen bonds than antiparallel strands.

Which of the following statements is false? In the beta sheet secondary structure the side chains are oriented perpendicular to the plane of the sheet, extending out from the plane on alternating sides In an alpha helix all of the hydrogen bonds lie parallel to the helix axis. Moreover, all of the carbonyl groups are pointing in one direction along the helix axis while the N-H groups are pointing in the opposite direction In an alpha helix, each hydrogen bond closes a loop containing 13 atoms In an anti-parallel beta sheet, an amino acid cannot bond directly (linearly) to the complementary amino acid in an adjacent chain as in the parallel beta sheet In the anti-parallel arrangement of a beta sheet the hydrogen bonds are aligned directly opposite each other, making for stronger and more stable bonds

Which of the following statements regarding beta sheets and/or beta turns is false? Beta sheets are rich in amino acids Leucine and Isoleucine. Beta turns are rich in amino acids such as Leucine and Isoleucine. anti-parallel beta sheets are more stable as compared to parallel beta sheets. Beta sheets are usually formed by inter-chain H-bonds.
