Does anyone have any background about this gene, CYP? It's been around for years now, but I'm really confuse as to what this actually does. I've been doing some research and different websites tell me different thing, some that contradicts with each other. For example, Cytochrome P450 1A1 or CYP1A1, is suppose to metabolize Xenobiotics(toxins), but then other websites tell me that it produces benzo pyrene, the Ultimate Carcinogen. I know the entire superfamily of CYP is used to metabolize toxins and fats, so does this one gene actually hurt us? Maybe it's my definition of metabolism, which in this context I believe it means to break down the toxin. So is it possible that by breaking down the toxin, our bodies are actually producing an even more dangerous carcinogen?
