Ionophores tributyltin
Several chemical factors affect the ionophore activity. The activity of an ionophore-metal complex depends on its geometric configuration and the coordinating sites and atoms which create coordination environment surrounding the metal center. This affects the selectivity and affinity towards a certain ion. Ionophores can be selective to a particular ion but may not be exclusive to it. Ionophores facilitate the transport of ions across biological membranes most commonly via pas… Web11 jan. 1999 · Ionophores Isoenzymes Protease Inhibitors Trialkyltin Compounds Water Pollutants, Chemical 1,2-bis (2-aminophenoxy)ethane N,N,N',N'-tetraacetic acid …

Triorganotins are also ionophores which mediate an exchange of Cl -, Br -, SCN - ,I -, or F - ions for OH - ions across biological and artificial phospholipid membranes.
Web1 aug. 2012 · Accordingly, at the end of each experiment cells were exposed to a series of calibration solutions containing the ionophores tributyltin (a Cl − /OH − exchanger; Sigma-Aldrich) and nigericin (a K + /H + exchanger; Sigma-Aldrich). Under steady-state conditions, [Cl −] o and [Cl −] i were assumed to be equal. WebThe Southern North Sea is the only assessment area for which trend information is available for three organotin compounds ( Figure 3 ): monobutyltin, dibutyltin and tributyltin. Trends in average sediment concentration for all three compounds in the Southern North Sea are decreasing, but still detectable.
