Webb27 sep. 2024 · Ligands that contain more than one binding site for a metal ion are called chelating ligands (from the Greek word χηλή, chēlē, meaning "claw"). As the name implies, chelating ligands have high affinity for metal ions relative to ligands with only one binding group (which are called monodentate = "single tooth") ligands. Webb10 nov. 2024 · Specifically, probiotic have been shown to reduce the absorption of HMs in the intestinal tract via the enhancement of intestinal HM sequestration, detoxification of HMs in the gut, changing the expression of metal transporter proteins, and maintaining the gut barrier function.
1.5: The Chelate Effect - Chemistry LibreTexts
WebbIn 1962 the first complex of flavonoids with aluminum as the central ion was received. Since 1980, researchers have been studied over 40 metal complexes of flavonoids [12]. Due to the specific chemical structure, flavonoids can chelate metal ions and form complexes. In addition to direct free radical scavenging properties, WebbIt can bind to a metal via two donor atoms at once. Bidentate binding allows a ligand to bind more tightly. Tridentate ligands, which bind through three donors, can bind even more tightly, and so on. This phenomenon is generally called the "chelate effect." This term comes from the Greek chelos, meaning "crab." ej u 6dk

WebbUnfortunately, EDTA can chelate several divalent cations, including Ca 2+, Zn 2+, Mg 2+, and Mn 2+, which are arguably the most common ion cofactors used by metalloproteases.

Although the factors responsible for metal ion chelationare not well understood in probiotic bacteria, it is revealed that the transition metal ion can inhibit enzyme-catalyzed phosphate ester displacement reactions and produce peroxyl and alkoxyl radicals by the decomposition of hydroperoxides .
