Epi-inositol is utilized in various research applications, particularly in the study of cellular signaling pathways and metabolic processes. It plays a role in understanding the function of inositol derivatives in biological systems, including their involvement in insulin signaling and lipid metabolism. This compound is also explored for its potential therapeutic effects, particularly in managing metabolic disorders such as diabetes and polycystic ovary syndrome (PCOS). Additionally, epi-inositol is used in plant biology research to investigate its role in stress responses and growth regulation. Its applications extend to the development of dietary supplements aimed at improving metabolic health and hormonal balance.
