University of Illinois professor of entomology May Berenbaum, who
led the study, said that many organisms use a group of enzymes called cytochrome P450 monooxygenases to break down
foreign substances such as pesticides and compounds naturally found in plants, known as phytochemicals.
Your immune system has a very sophisticated system for keeping you safe that
leads it to identify all of the
foreign substances that enter your body or that you come into contact with.
