WebNov 24, 1995 · To demonstrate that there are at least real intrinsic phi propensities, independent of context effects, we have used two different nuclear magnetic resonance parameters related to the phi dihedral angle (J3 alpha HN coupling constants and the chemical shift of the C alpha H proton), determined in random-coil tetra- and … http://guweb2.gonzaga.edu/faculty/cronk/CHEM245pub/L07.html
WebSep 3, 1999 · The alpha helix is a type of regular secondary structure in which successive amino acids adopt the same Phi and Psi dihedral angles (peptide bonds all trans). It is a coiled structure characterized by 3.6 residues per turn, and translating along its axis 1.5 angstrom per amino acid. Thus the pitch is 3.6x1.5 or 5.4 angstrom. http://cib.cf.ocha.ac.jp/bitool/DIHED2/
