[APD] Rotating humic acid, 3D chelating agents, etc.

[Darrell Fennell <dkfennell at yahoo_com>]

For those who need a closer look at a humic acid
molecules, want to know how ion carriers work, or are
curious what EDTA (with and without Fe) looks like,
take a look at this gallery:

make sure to download the "Chime" program so you can
rotate the molecules in 3D.

Cheers,
