Cytochrome P450 oxidases are important enzymes in xenobiotic metabolism.. Xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as drugs and poisons.
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
Although the body is able to remove xenobiotics by reducing it to a less toxic form through xenobiotic metabolism then excreting it, it is also possible for it to be converted into a more toxic form in some cases. This process is referred to as bioactivation and can result in structural and functional changes to the microbiota. [2]
Pharmacogenetics, defined as the identification and functional characterisation of polymorphic genes that encode xenobiotic metabolising enzymes and transporters that may result in altered enzymatic, cellular and clinical responses to xenobiotics.
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Clinicians use drug detoxification to reduce or relieve withdrawal symptoms while helping an addicted person adjust to living without drug use. Drug detoxification does not aim to treat addiction but rather represents an early step within long-term treatment. Detoxification may be achieved drug-free or may use medications as an aspect of treatment.
A xenobiotic-sensing receptor is a receptor that binds xenobiotics. [1] They include the following nuclear receptors: [1] Constitutive androstane receptor (CAR) Pregnane X receptor (PXR) CAR and PXR are xenobiotic receptors and they both are members of NR1I nuclear receptor family. The regulate the metabolic pathway for the elimination of ...
Drug detoxification (informally, detox) is variously construed or interpreted as a type of "medical" intervention or technique in regards to a physical dependence mediated by a drug; as well as the process and experience of a withdrawal syndrome or any of the treatments for acute drug overdose (toxidrome).
