The cytochrome p450
WebCytochrome P4502E1 (CYP2E1) was originally designated the microsomal ethanol-oxidizing system. It associates with NADPH-cytochrome P450 reductase in the microsomal membrane and reduces molecular oxygen to water as ethanol is oxidized to acetaldehyde. CYP2E1 has a high K m for ethanol; thus it has a greater role when blood ethanol levels … WebMay 10, 2024 · We therefore developed cells that mimicked the activities of cytochrome P450 1A2 (CYP1A2), CYP2C9, CYP2C19, CYP2D6, and CYP3A4, which strongly contribute to drug metabolism in human hepatocytes, and established a system to assess the inhibitory activity of health foods toward P450-mediated metabolism. We simultaneously infected …
