Formation of mutagens in cooked foods. III. Isolation of a potent mutagen from beef.
The major mutagenic component of fried beef has been isolated using a series of chromatographic steps. The pure compound has been analyzed by low and high resolution mass spectroscopy and nuclear magnetic resonance spectroscopy. The results indicate that the molecular weight of this extremely mutagenic compound is 198, with an elemental composition of C11H10N4. The compound is different from the known mutagenic pyrolysis products of amino acids or proteins.
