Webb10 apr. 2024 · The psi bond is between the alpha carbon and the carbonyl carbon. Each amino acid residue in the peptide chain therefore has one phi and one psi bond, each of which can exist in three stable bond angles. Therefore, for a 100-residue peptide, there are 198 phi and psi bonds and so 3^198 possible conformations. Webb24 nov. 1995 · It has been indicated that amino acids have various intrinsic phi and psi propensities, as demonstrated from the comparison between experimental secondary structure propensities and their relative statistical distribution in the protein database for the appropriate region of the Ramachandran plot. cred factsheet
