Campesterol is widely used in the pharmaceutical industry as a precursor for the synthesis of steroid hormones and other bioactive compounds. It plays a significant role in research related to cholesterol metabolism, as it is structurally similar to cholesterol and can help in understanding lipid absorption and regulation in the human body. Additionally, campesterol is utilized in the development of plant sterol-enriched functional foods and dietary supplements aimed at reducing LDL cholesterol levels, thereby supporting cardiovascular health. Its incorporation into skincare products is also notable, where it is valued for its anti-inflammatory and skin-soothing properties. In agriculture, campesterol is studied for its potential role in plant growth regulation and stress response mechanisms.
