(Phys.org)—Macrocyclic and chelating molecules are important in physiological processes and pharmaceuticals. Hemoglobin, for example, is a chelating molecule in which iron is coordinated to donor atoms in a porphyrin ring. ...
Like a bull in a china shop, a massive, iodine-based ion called iodate should disrupt the surrounding water molecules until it is forcibly expelled. However, it doesn't. This disconnect between the molecule's attributes and ...
