WebAbstract Aligned alpha helix peptide dipoles sum to a "macroscopic" dipole parallel to the helix axis that has been implicated in protein folding and function. WebCapping is a property at specific positions at the end of the helix - the dipole is an emergent property of the helical geometry. The dipole comes from the fact that all the -NH on the peptide bond (generally postitive) point one way, and all the oxygens (generally negative) point another way - leading to a dipole moment along the helical axis.
