Medical Definition of Aflatoxin b1
1.
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, cotton seed 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.
