Di-DHA charge density around the hexaenoic motive, calculated by Hyperchem version 8. This molecular dynamic model of di-DHA supports the idea that di-DHA has a specific role in energy transduction. The light blue atoms are carbon, the white atoms are hydrogen, the red atoms are oxygen, the dark blue atom is nitrogen, and the yellow atom is phosphorus. The complexity of the total charge density, however, clearly rests in the cis-double bond region containing two DHA moieties. The orbital positive charge density is labeled pink, negative is labeled green. Pi bonding total charge density above versus below the molecular plane are not perfectly symmetrical.
