Glucuronidation constitutes an important pathway in the phase II metabolism of the mycotoxin zearalenone (ZEN) and the growth promotor α-zearalanol (α-ZAL, zeranol), but the enzymology of their formation is yet unknown. In the present study, ZEN, α-ZAL and four of
A simple analytical scheme for the screening and quantification of zearalenone and its metabolites, alpha-zearalenol and beta-zearalenol, is reported. Extracts from maize flour samples were collected by supercritical fluid extraction and afterwards, they were analyzed by CE with amperometric detection.

The disposition of [3H]zeranol has been studied in the female Wistar rat, New Zealand rabbit, beagle dog, rhesus monkey and man. The blood elimination half-life of total radioactivity in rabbit was 26 h, monkey 18 h and man 22 h.

The enzymes 3alpha- and 3beta-hydroxysteroid dehydrogenase (3alpha- and 3beta-HSD) play a pivotal role in synthesis of various steroid hormones including oestradiol and testosterone. The structure of the mycotoxin zearalenone resembles many characteristics of steroids and binds to oestrogen receptors as
