. Examples include pesticides dyes industrial pollutants. Most pharmacological agents are lipophilic and their elimination from the body is facilitated by enzymatic modifications to render them more hydrophilic. Examples of these xenobiotics can be found in ambient and occupational exposures including water pollutants such as dibutyl phthalates DBPs persistent organochlorine pollutants polychlorinated biphenyl pesticides DBCP malathion atrazine and.
Xenobiotics are foreign chemical substances reported in an organism which do not occur naturally or normally in that targeted organism. Xenobiotic substances are an issue for sewage treatment systems since they are many in number and each will present its own problems as to how to remove them and whether it is worth trying to Some xenobiotics substances are resistant to degradation. Some naturally occurring chemicals endobiotics become xenobiotics when present in the environment at excessive concentrations.
The proportion of these xenobiotics whose metabolism has been established in Man and laboratory animals is trivial. The meaning of XENOBIOTIC is a chemical compound such as a drug pesticide or carcinogen that is foreign to a living organism.

The liver is a major site for xenobiotic metabolism. These natural food toxins are adversely affecting health of millions most of them unaware of what is causing - or contributing to - their health problem. Without metabolism many xenobiotics would reach toxic concentrations.
Most metabolic activity inside the cell requires energy cofactors and enzymes in order to. A xenobiotic is a chemical compound identified within an organism that was not created naturally or. Xenobiotics are all those elements and compounds that have a chemical structure that could not have arisen naturally said compounds have been the product of a previous development by the man in laboratories equipped and specialized in this field this way it is it is called synthetic compounds and their purposes can be of all kinds as for the field of medicine in medicines and.
Xenobiotics are substances that are foreign to an entire biological system so that biological system can either be a living organism or a biota. 29 rows Xenobiotics are defined as chemical compounds that are present in but foreign to biologic systems. The xeno in xenobiotics comes from the Greek word xenos meaning guest friend or foreigner.
General xenobiochemistry including in vitro studies concerned with the metabolism disposition and excretion of drugs and other xenobiotics as well as the structure function and regulation of. Xenobiotics are molecules that are introduced into the body from the environment and subsequently metabolized by the body. The xenobiotic compounds are either not produced naturally or are produced at much lower concentrations than man.
Meaning of Xenobiotic Compounds. A form of nutrient. More than 52 million organic and inorganic substances have been synthesized of which over 39 million are commercially available and thus represent potential human exposures.
Examples can be pollutants and their effects on the biota or foreign compounds like carcinogens drugs food additive and pesticides and environmental pollutants within an organism body. Xenobiotic metabolism can be defined as chemical transformation by a biological system usually via DMEs which typically converts relatively lipophilic compounds into more readily excreted hydrophilic metabolites. The unwanted and harmful chemical agents might go into the human body via numerous paths such as breathing ingestion skin contact and so on.
