WebThe structure of four ionophores used as anticoccidials, monensin, salinomycin, lasalocid and narasin are given in Table 1. Maduramycin is a further compound currently in use at 5 ppm in feed (Kantor et al., 1984). The ionophores have a wide spectrum of activity, but rather a narrow range of safety. However, despite reported monensin-resistant ... WebThe available chemical toolbox of suitable chelating compounds is unfortunately limited because many promising complexing agents are not water soluble. We introduce here a novel class of complexometric titration reagents, a suspension of polymeric nanospheres whose hydrophobic core is doped with lipophilic ion-exchanger and a selective …
Rapid and Reliable Identification of Ionophore Antibiotics in …
Ionophores are chemical compounds that reversibly bind and transport ions through biological membranes in the absence of a protein pore. This can disrupt the membrane potential, and thus these substances could exhibit cytotoxic properties. Ionophores modify the permeability of biological … Meer weergeven In chemistry, an ionophore (from Greek ion and -phore 'ion carrier') is a chemical species that reversibly binds ions. Many ionophores are lipid-soluble entities that transport ions across the cell membrane. Ionophores Meer weergeven 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 … Meer weergeven • Fluka ionophores for ion-selective electrodes • Medical Information database Reference.MD • Structures and Properties of Naturally Occurring Polyether Antibiotics, J. Rutkowski, B. Brzezinski; open access review article Meer weergeven Biological activities of metal ion-binding compounds can be changed in response to the increment of the metal concentration, and based on the latter compounds can be classified as "metal ionophores", "metal chelators" or "metal shuttles". If … Meer weergeven Ionophores are widely used in cell physiology experiments and biotechnology as these compounds can effectively perturb … Meer weergeven • Siderophore • Protonophore • Chelation Meer weergeven WebWe have found that the addition of ammonium acetate to the HPLC mobile phase, in conjunction with ‘cone voltage’ or ‘skimmer’ assisted fragmentation, is a convenient way of producing additional diagnostic ions from polyether ionophore compounds, without compromising the overall sensitivity. popeyes number 9
