Alkaline earth metal ions, alginic acid binding

Solution and Solid State NMR Studies of Alginic Acid Binding with Alkaline Earth, Lanthanide, and Yttrium Metal Ions... 

Preliminary studies of depolymerized alginic acid indicate that the GG-preference of the divalent alkaline earths remains in mixtures of homopolymeric blocks. One conclusion from our data might be that there is a minimum chain length required for maximum metal ion binding. Until further studies are completed, the extent of binding for the divalent ions and depolymerized alginate cannot be determined.
