Theoretical study for determining the type of interactions between a GG block of an alginate chain with metals Cu2+, Mn2+, Ca2+ and Mg2+

The alginate interaction with divalent cations has been the subject of extensive study since this biopolymer forms hydrogels in the presence of divalent cations (ionic crosslinking), which exhibit important properties with applications in fields such as medicine. It has been proposed that the properties of the hydrogel formed from the ionic crosslinking process depend, among several factors, on the type of interactions between the polymer and...
