WebWhat are ionophores? Ionophores are lipid-soluble molecules, usually synthesized by microorganisms to transport ions through a lipid bilayer of cell membrane. Ion Transport Ionophores function as ion carriers. Ion carriers can transfer ions from a hydrophilic medium, such as water, into a hydrophobic medium, i.e a biological membrane, where … Web12 aug. 2024 · This article describes selected historical milestones in the field of neutral …

Web30 sep. 2015 · Dear Colleagues, Ionophore-based potentiometric sensors or ion-selective electrodes (ISEs) are chemical sensors where host-guest chemistry is utilized to achieve high selectivity to specific ions of interest. A unique feature of ISEs is that they provide information about the free ion concentration (ion activity), which is highly relevant in, e ...

WebIonophore antibiotics are fermentation products of different Streptomyces species and other fungi. They are polyether antibiotics, which exert their antibiotic action by disrupting the transport of ions in the cell membranes. Ionophores are widely used in cell physiology experiments and biotechnology as these compounds can effectively perturb gradients of ions across biological membranes and thus they can modulate or enhance the role of key ions in the cell. Many ionophores have shown antibacterial and antifungal … 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 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. … Meer weergeven • Siderophore • Protonophore • Chelation 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 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.
