beta-zearalenol beta-zearalenol β-zearalenol is a nonsteroidal estrogen of the resorcylic acid lactone group related to mycoestrogens found in fusarium spp. it is the β epimer of α-zearalenol and along with α-zearalenol is a major metabolite of zearalenone formed mainly in the liver but also to a lesser extent in the intestines during first-pass metabolism. a relatively high proportion of α-zearalenol is formed from zearalenone compared to β-zearalenol in humans. β-zearalenol is about the same or slightly less potent as an estrogen relative to zearalenone. β-zearalenolclinical dataother namesbeta-zearalenol; beta-trans-zearalenolidentifiers iupac name (2e,7s,11s)-7,15,17-trihydroxy-11-methyl-12-oxabicyclooctadeca-1(18),2,14,16-tetraen-13-one cas number71030-11-0pubchem cid6437352chemspider5908979unii35e809pp7okeggc14751chebichebi:35072comptox dashboard (epa)dtxsid8022533 echa infocard100.190.517 chemical and physical dataformulac18h24o5molar mass320.385 g·mol−13d model (jsmol)interactive image smiles c1ccc(ccc/c=c/c2=cc(=cc(=c2c(=o)o1)o)o)o inchi inchi=1s/c18h24o5/c1-12-6-5-9-14(19)8-4-2-3-7-13-10-15(20)11-16(21)17(13)18(22)23-12/h3,7,10-12,14,19-21h,2,4-6,8-9h2,1h3/b7-3+/t12-,14-/m0/s1key:fpqfyiaxqdxnor-pmraarrbsa-n
