Computational chemistry is the branch of theoretical chemistry whose major goals are to create efficient computer programs that calculate the properties of molecules (such as total energy, dipole moment, vibrational frequencies) and to apply these programs to concrete chemical objects.

A right-handed spiral conformation; the a-helix has a pitch of 5.4 A and has 3.6 amino acid residues per turn; every main chain C=O and N-H group is hydrogen-bonded to a peptide bond 4 residues away; the peptide planes are roughly parallel with the helix axis and the dipoles within the helix are aligned, i.e. all C=O groups point in the same direction and all N-H groups point the other way; side chains point outward from helix axis and are generally oriented towards its amino-terminal end.
