How does biotransformation of an organic xenobiotic work?

The biotransformation of organic xenobiotics usually begins with the first oxidation phase (phase I), which introduces the reactive group into the xenobiotics, and with the second phase of conjugation (phase II) with a non-toxic endogenous metabolite, which leads to its release. of the product.

This use results in mineralization fractions in the literature that can range from -35 to ≈0 depending on the rate limiting degree (Delwiche and Steyn, 1970 Feigin et al., 1974 Letolle, 1980). The large fractionation is due to the nitrification of ammonium rather than the conversion of organic nitrogen to ammonium.

How are the different types of mineralization different?

Mineralization can be classified into different categories based on the following criteria: organisms or processes that create the chemical conditions necessary for mineral formation, the origin of the substrate at the site of mineral deposition, and the degree of control that the substrate has in terms of morphology, composition and growth.

Why is biotransformation not required for xenobiotics?

In contrast, xenobiotics with high water solubility generally do not require biotransformation due to their rapid excretion in the urine. Usually, two or more sequential enzymatic reactions are required to convert lipophilic chemicals into metabolites that are efficiently removed from the body.

How is biotransformation related to metabolism and metabolic transformation?

Biotransformation refers to the process by which lipophilic (fat-soluble), xenobiotic (foreign), or endobiotic (endogenous) chemicals in the body are converted into more hydrophilic (water-soluble) products through enzymatic reactions. In this context, metabolism and metabolic transformation are synonymous with biotransformation.

How is oxidation catalyzed in the metabolism of xenobiotics?

Oxidation is a very frequent phase in the metabolism of xenobiotics. In most cases, it is catalyzed by a superfamily enzyme system called cytochrome P450. This superfamily is now known to consist of about 20 enzyme families. The genes and thus the amino acid composition of these enzymes are linked together.
