In addition, one ion can bind in the cavity at a site called SC or one or more ions at the extracellular side at more or less well-defined sites called S0 or Sext.
Large ions and less highly charged ions bind water less tightly and have smaller hydrated radii than smaller, more highly charged ions.
Upon impact the ions may interact with and chemically bind to species present at the surface.
The inhibition by Al and Mn is more severe than can be explained by simple displacement, hence it is possible that these ions bind to the Mg uptake system directly.
Chelation describes a particular way that ions and molecules bind metal ions.
Formation of inner sphere complexes occurs when ions bind directly to the surface with no intervening water molecules.
The ion, two electrons bound electrostatically with a proton, and the antiproton have the same charge and can therefore be simultaneously trapped.
These ions bind to type 2 and type 3 copper and disrupts electron transfer via copper centers, therefore reduces activity.
The molecule or ion to be transported (the substrate) must first bind at a binding site at the carrier molecule, with a certain binding affinity.
For simplicity most DNA molecular models omit both water and ions dynamically bound to B-DNA, and are thus less useful for understanding the dynamic behaviors of B-DNA in vivo.
