WebNature - The helical hydrophobic moment: a measure of the amphiphilicity of a helix WebThe first moment, or hydrophobic dipole moment, is the analogue of the electric dipole moment of a cluster of charges. Just as the electric dipole moment measures the asymmetry of the charge distribution, the hydrophobic dipole moment measures the amphiphilicity (asymmetry of hydrophobicity) of the structure.
