Myoinositol

Molecular classification
Cyclic carbohydrate, Cyclohexanehexol, Inositol
01

Overview

Myoinositol is a naturally occurring cyclic carbohydrate crucial for cell signaling, lipid metabolism, and insulin sensitivity. It serves as a precursor for phosphatidylinositol and phosphoinositides. While not a direct drug target, it is supplemented to address conditions like PCOS, metabolic syndrome, and insulin resistance. It plays a role in FSH signaling and potentially mood regulation.

02

Mechanism of action

Myoinositol itself is not directly targeted by drugs. It acts as a supplement to influence metabolic and signaling pathways.
