nonchelating
Nonchelating refers to a property of certain substances, primarily molecules, that describes their inability to form stable complexes with metal ions through the process of chelation. Chelation is a chemical process where a molecule, known as a ligand, binds to a central metal atom at two or more points. These points of attachment are often through atoms that can donate electron pairs, such as oxygen, nitrogen, or sulfur. The resulting structure forms a ring-like formation, which is often very stable.
Substances that are nonchelating, in contrast, lack the necessary functional groups or the spatial arrangement to
