An ionophore produced by Streptomyces conglobatus, it is used in research to raise the intracellular level of Ca(2+) and as a research tool to understand Ca(2+) transport across biological membranes. It has a role as a metabolite and a calcium ionophore. It is an enol, a cyclic ether, a very long-chain fatty acid and a polyunsaturated fatty acid."}]
