Beschreibung
α-Zearalenol is a major hepatic metabolite of zearalenone , a mycotoxin produced by fungi in food and animal feeds. It is a less potent agonist of estrogen receptors than the parent compound. However, α-zearalenol has pronounced effects on uterotropic activity, sperm motility, and preimplantation embryonic development.

Verwenden
α- Zearalenol may be used as an analytical reference standard for the determination of the analyte in traditional medicinal herbs, human and animal urine by various chromatography techniques.
Verwenden
α-Zearalenol is a mycotoxin produced by several species of Fusarium. α-Zearalenol exhibits pronounced estrogenic activity, being 3-fold more active than zearalenone. Contamination of grains, notably maize, by Fusarium species gives rise to high levels of zearalenol and is regarded as an important food quality issue for both humans and animal health.
Definition
ChEBI: Alpha-Zearalenol is a macrolide.
Biochem/physiol Actions
α-Zearalenol (α-ZOL) is a catabolite of zearalenone, synthesized majorly in granulosa cells, intestine and liver in pigs. It has estrogenic functionality. α-ZOL inhibits sperm motility in horse possibly by eliciting genotoxic effect. α-ZOL displays higher affinity towards estrogenic receptors.
in vitro
the binding characteristic of α-zea was less potent with estrogen receptors than the parent compound [2]. α-zearalenol showed pronounced effects on uterotropic activity [3]. α-zea inhibited normal sperm motility, but stimulated hyperactive motility in the remaining motile cells and simultaneously induced the acrosome reaction [4].
