α-Zearalenol is anonsteroidalestrogen of theresorcylic acid lactone group related tomycoestrogens found inFusarium spp.[1] It is the α-epimer ofβ-zearalenol.[2] Along with β-zearalenol, it is a majormetabolite ofzearalenone formed mainly in theliver but also to a lesser extent in theintestines duringfirst-pass metabolism.[2][3] A relatively low proportion of β-zearalenol is metabolized from zearalenone compared to α-zearalenol in humans.[3] α-Zearalenol is about three to four times more potent as an estrogen relative to zearalenone.[1]
