| Direct sensing mechanisms might involve proteins or ligands that bind or react with oxygen. |
| Furthermore, the molecular arrangement of the three citrate ligands allows the possible introduction of other catalytic metal centres. |
| Ligand field theory, like crystal field theory, concentrates on what happens when ligands split the central metal atom's inner orbitals. |
| Special care was taken to include all the hydrogen bonds between the zinc ligands and the surrounding residues. |
| Inside the human body, there are mu, Kappa, and delta opiate receptors, to which the enkephalins and endorphins bind as ligands. |
| The molecules or anions attached to the central atom are called coordinating groups or ligands. |
