Their work with chlorophylls (especially the synthetic, water-soluble derivatives known as chlorophyllins) indicates that these plant-derived compounds can inhibit the production of potentially carcinogenic abducts by a number of dietary carcinogens--from polycyclic aromatic hydrocarbons in char and aflatoxin in moldly grains to HCAs in cooked meats.
The likely culprit, scientists eventually deduced, was the intrinsic infrared emission from a class of organic molecules known as polycyclic aromatic hydrocarbons (PAHs), which, scientists would later discover, are amazingly plentiful; nearly 10 percent of all the carbon in the universe is tied up in PAHs.
