Lanosterol plays a crucial role in the biosynthesis of cholesterol and other sterols in the body. It is a key intermediate in the mevalonate pathway, which is essential for producing various biomolecules. In ophthalmology, lanosterol has shown potential in treating cataracts by dissolving protein aggregates in the eye lens, offering a non-surgical approach to cataract management. Additionally, it is being researched for its anti-inflammatory and skin barrier repair properties, making it a candidate for use in skincare products to improve skin health and reduce inflammation. Its role in cellular processes also makes it a subject of interest in studies related to cancer and cholesterol regulation.
