WebNov 11, 2024 · Statins and HMG-CoA Reductase Statins are commonly prescribed as lipid-lowering agents, serving as protective agents in cardiovascular diseases. A wide range of their beneficial effects, including cholesterol-independent mechanisms, has resulted in statins being one of the most prescribed groups of drugs [ 36 ]. WebHMG-CoA reductase is an integral protein of the endoplasmic reticulum. Its C-terminal segment contains the catalytic site, which is located in the cytosol. HMG-CoA reductase is the primary target for regulation of nonsterol isoprenoid derivatives and cholesterol. HMG-CoA reductase is regulated both by short-term and long-term biochemical processes. is tacoma worth visiting
