|Xenobiotics as the name signifies âstrangersâ are compounds that are foreign to human body. Xenobiotic compounds include natural as well as synthetic compounds such as pesticides, drugs, additives, heavy metals, food additives etc. The accumulation of these compounds in the body will cause depletion of cells and adverse effect on metabolism. In lower doses some of the Xenobiotic compounds have beneficial functions such as pharmaceutical and drug activities. Food and medication is the common pathway of Xenobiotic entry into body. Xenobiotic compounds enter the cells through diffusion, active transport and endocytosis. The metabolism of the Xenobiotics occurs mainly in liver.
