Description: A xenobiotic is a chemical compound that is foreign to a living organism, meaning it is not naturally produced or metabolized by that organism. These compounds can include a wide variety of substances, from drugs and pesticides to environmental pollutants. The presence of xenobiotics in an organism can trigger biological responses ranging from detoxification to adverse effects, depending on the nature of the compound and the organism’s ability to handle it. In the field of bioinformatics, xenobiotics are studied to understand how they interact with biomolecules and biological systems, which can help predict their toxicity and health effects. In biochemistry, research focuses on how xenobiotics are metabolized by the organism’s enzymes, influencing their efficacy and safety. Toxicology centers on the harmful effects these compounds can have on organisms, which is crucial for risk assessment and chemical regulation. In summary, xenobiotics represent a multidisciplinary area of interest that spans from basic research to practical applications in health and the environment.
