alpha-zearalenol alpha-zearalenol α-zearalenol is a nonsteroidal estrogen of the resorcylic acid lactone group related to mycoestrogens found in fusarium spp. it is the α epimer of β-zearalenol and along with β-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 low proportion of β-zearalenol is formed from zearalenone compared to α-zearalenol in humans. α-zearalenol is about 3- to 4-fold more potent as an estrogen relative to zearalenone. α-zearalenolclinical dataother namesalpha-zearalenol; trans-zearalenol; 2,4-dihydroxy-6-(6α,10-dihydroxy-trans-1-undecenyl)benzoic acid μ-lactoneidentifiers iupac name (2e,7r,11s)-7,15,17-trihydroxy-11-methyl-12-oxabicyclooctadeca-1(14),2,15,17-tetraen-13-one cas number36455-72-8pubchem cid5284645chemspider4447689unii59d4evj5kckeggc14750chebichebi:35065chemblchembl371463comptox dashboard (epa)dtxsid8022402 echa infocard100.264.264 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-qdklysgjsa-n
