Displaying 4 results of Campesterol Stable Isotopes Campesterol is a plant sterol found in various natural sources including soybeans, corn, and wheat germ. Stable isotopes of campesterol can be used as tracers in metabolic studies. They are chemically identical to the non-isotopic form but have a unique atomic mass, making them useful for tracking the fate of campesterol in biological systems. The use of stable isotopes in metabolic studies has become increasingly popular in recent years due to their accuracy and reliability.
