Theophylline is metabolized extensively in the liver. [2] It undergoes N-demethylation via cytochrome P450 1A2. It is metabolized by parallel first order and Michaelis-Menten pathways. Metabolism may become saturated (non-linear), even within the therapeutic range. Small dose increases may result in disproportionately large increases in serum ...

The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. CYP1A2 localizes to the endoplasmic reticulum and its expression is induced by some polycyclic aromatic hydrocarbons (PAHs), some of which are found in cigarette smoke.
Cytochrome P450 2E1 (abbreviated CYP2E1, EC 1.14.13.n7) is a member of the cytochrome P450 mixed-function oxidase system, which is involved in the metabolism of xenobiotics in the body. This class of enzymes is divided up into a number of subcategories, including CYP1, CYP2, and CYP3, which as a group are largely responsible for the breakdown ...
Nelly Furtado is ignoring the popular "New Year, New Me" mantra!. On Sunday, Jan. 5, the singer, 46, shared two photos of herself on Instagram wearing a bright orange bikini alongside an inspiring ...
CYP1A1 also metabolizes polyunsaturated fatty acids into signaling molecules that have physiological as well as pathological activities. CYP1A1 has monoxygenase activity in that it metabolizes arachidonic acid to 19-hydroxyeicosatetraenoic acid (19-HETE) (see 20-Hydroxyeicosatetraenoic acid) but also has epoxygenase activity in that it metabolizes docosahexaenoic acid to epoxides, primarily ...
The 67-year-old posted the #Flashback video to Instagram earlier this week to motivate her followers with some whole-body exercises. In the video, Austin uses a pair of light hand weights to amp ...
Ajahzi’s body changed, but “I didn’t feel good,” she says. Then macro tracking became popular, and Ajahzi went all in, giving up her social life to stay the course. When friends went out ...
