How can we prove that the supernatural or paranormal doesn't exist? He also noted that hot nitric acid does not attack cinnabar, whereas it quickly turns precipitated "mercurous sulfide" to mercuric nitrate without leaving any residue. When we discuss hard or soft "bases", we are discussing ligands. receding from us at half the speed of light (or greater). Though this naming convention has been largely abandoned by the scientific community, it remains in use by some segments of industry. Because there are three of these groups in enterobactin, and there is enough space in between for the groups to fold around a central atom, enterobactin is a chelating (hexadentate) donor with a high binding constant. Example 2 -ous ending is used for the lower oxidation state -ic ending is used for the higher oxidation state Example 3 Calmodulin, which aids in calcium uptake, uses hard oxygen donors in aspartate and glutamate to bind to the Ca, Enterobactin (below) is a molecule used by certain bacteria to bind iron(III) and transport it into the cell.
