1) Atomic orbitals of carbon relative to methane in a cubic frame of reference.
2) Atomic orbital combination giving rise to bonding molecular orbitals for methane.
The isoelectric point (pI) of a peptide is the pH at which the peptide does not migrate in an electric field. Since the peptide is zwitterionic, there are the same number of positive charges as negative charges on the peptide population.
