Inositol stable isotopes are a powerful analytical tool used in metabolic research to investigate the biological pathways associated with inositol metabolism. These isotopes are non-radioactive and do not decay over time, allowing for precise and accurate measurements of inositol metabolism in vivo. Through the use of isotopically labeled inositols, researchers can track the fate of inositol within the body and gain insights into the mechanisms underlying various diseases such as diabetes and cancer.
