Trans-C75 is primarily used in research settings to study metabolic processes and energy regulation. It acts as an inhibitor of fatty acid synthase (FAS), an enzyme crucial for the synthesis of fatty acids. By blocking FAS, trans-C75 helps researchers investigate the role of fatty acid metabolism in conditions like obesity, cancer, and metabolic disorders. Its ability to suppress appetite and reduce body weight in experimental models has made it a valuable tool for understanding the relationship between lipid metabolism and energy balance. Additionally, trans-C75 is utilized in studies exploring potential therapeutic strategies for cancers that rely heavily on fatty acid synthesis for growth and survival. Its application provides insights into metabolic pathways and their impact on health and disease.
