Iron ionophores and chelating agents are collectively called siderophores. Synthetic ionophores. Many synthetic ionophores are based on crown ethers, cryptands, and calixarenes. 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.
