A substance formed when zearalenone is broken down in the digestive tract of animals. More potent than zearalenone.
Zearalenone is converted to β-zearalenol, in the digestive tract of animals (α-zearalenol is also formed from zearalenone). Less β-zearalenol is formed from zearalenone than α-zearalenol. β-zearalenol has a lower affinity for oestrogen receptors than zearalenone, but is toxic to endometrial cells.
