Lipid Biosynthesis Mechanism of Statins & Inhibiting CoQ Synthesis
In this video, we will discuss the general isoprenoid biosynthesis and processing pathways and how statin medications fit into the big picture (e.g., HMG-CoA Reductase). We will see how statins disrupt Coenzyme Q and vitamin D synthesis.
