Preferred Label : aflatoxin B1;
MeSH definition : A potent hepatotoxic and hepatocarcinogenic mycotoxin produced by the Aspergillus
flavus group of fungi. It is also mutagenic, teratogenic, and causes immunosuppression
in animals. It is found as a contaminant in peanuts, cottonseed meal, corn, and other
grains. The mycotoxin requires epoxidation to aflatoxin B1 2,3-oxide for activation.
Microsomal monooxygenases biotransform the toxin to the less toxic metabolites aflatoxin
M1 and Q1.;
