WebNov 4, 2010 · Full-text Abstract Zearalenone (ZEA) is a macrocyclic β-resorcylic acid lactone produced by numerous species of Fusarium. It frequently contaminates corn and cereal products in many regions of the world. The biological activity of ZEA is dominated by its pronounced oestrogenicity, which is even enhanced in certain reductive metabolites. WebResorcylic acid lactones are a group of estrogenic compounds. They are lactones of resorcylic acid. Examples include the mycoestrogens (and synthetic analogues) …
