Web13 apr. 2024 · As seen in Fig. 7, the absorbed peaks of both antiparallel β-sheet and α-helix spectra shifted to lower frequency when the C O bond force constant was reduced. Interestingly, when k f b = 515 kcal/mol/Å 2 the absorbed peaks of the β-sheet and α-helix spectra are 1633 cm −1 and 1654 cm −1 , which are the same as the experimental … WebKirtikumar Patel, in De Novo Peptide Design, 2024. 1.3.4 All α-helix protein design. Helix is the other important protein secondary structure in which hydrogen bonding pattern distinguishes α-helix (φ=−57 degrees, ψ=−47 degrees and i to i+4 hydrogen bonding) from the closely related 3 10 helix (φ=−50 degrees, ψ=−30 degrees and i to i+3 … front brake pads and discs
