Cholic Acid 7-sulfate is utilized primarily in biomedical research to study bile acid metabolism and its role in liver function. It serves as a critical marker for understanding the pathways of bile acid synthesis and excretion, which are vital for diagnosing and managing liver diseases. Additionally, this compound is used in the development of therapeutic agents targeting bile acid-related disorders, such as cholestasis and certain metabolic syndromes. Its application extends to the study of gut microbiota interactions, where it helps in exploring the impact of bile acids on microbial communities and their influence on host health.
