sterol metabolic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways involving sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule. [ISBN:0198547684]
Sterol metabolic process encompasses a complex and multifaceted pathway essential for the biosynthesis, modification, and degradation of sterols, a class of lipid molecules that play crucial roles in cell structure, signaling, and membrane integrity. The process begins with the synthesis of squalene from acetyl-CoA, a key precursor molecule. Squalene is then cyclized into lanosterol, the first sterol intermediate, through a series of enzymatic reactions. Lanosterol undergoes a series of modifications, including demethylation, reduction, and isomerization, to produce cholesterol, the primary sterol in animals. Cholesterol is a structural component of cell membranes, contributing to their fluidity and stability. It also serves as a precursor for the synthesis of steroid hormones, such as testosterone, estrogen, and cortisol, which regulate diverse physiological functions. In addition to cholesterol synthesis, the sterol metabolic process involves the degradation of cholesterol through a series of enzymatic steps. This process, known as cholesterol catabolism, primarily occurs in the liver and involves the conversion of cholesterol into bile acids, which are essential for fat digestion. Sterol metabolic process is tightly regulated at multiple levels, ensuring the appropriate levels of sterols in the body. Dysregulation of this pathway can lead to various health problems, including cardiovascular disease, cancer, and neurological disorders. The intricate nature of sterol metabolism highlights its fundamental importance in maintaining cellular function and overall health.'

| rifampin | Rifampin: A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms.
