Admittedly, this made me wonder the extent to which perceptions and subsequent descriptions of this style are influenced purely by the way the beer looks- like. Biotransformation of a toxin occurs in several steps. Although it is the largest organ of the human body, skin is often not considered in discussions of drug metabolism. However, there is growing evidence that most common drug-metabolizing enzymes are expressed in the skin

Biotransformation: Introduction, Importance, Types

Biotransformation is significantly affected by a number of factors, these include:. 1. Enzyme Induction: When drugs given over prolonged period of time, upregulation of enzymes takes place. Most of the time cytochrome P450 is involved leading to increased synthesis of new enzymes. The rate of metabolism increases as enzyme induction takes place Biotransformation can only therefore be applied to the mineralisation step of any oxo-biodegradable polymer, when we examine the steps of oxo-biodegradability this perfectly describes the second step of mineralisation, detailed in ASTM6954-18. The first step common with all materials described as oxo-biodegradable is oxidation of the macro.
