Lanosterol is a natural organic compound that serves as a precursor in the biosynthesis of cholesterol and other sterols. It is produced in the body from squalene through a series of enzymatic reactions. Lanosterol plays a crucial role in the formation of cell membranes and the production of steroid hormones. In addition to its biological significance, lanosterol has gained attention for its potential therapeutic applications. Research suggests that it may have a role in treating certain conditions, such as cataracts, by influencing the crystallization of proteins in the eye. Further studies are ongoing to explore its full range of benefits.
