Metabolite Identification

Common Name

(E)-ascladiol

Description

(E)-ascladiol is a secondary alcohol belonging to the class of organic compounds known as terpenoids. It is a metabolite that plays a role in various biochemical pathways, particularly in the reduction of potentially toxic compounds. In a study utilizing AI-assisted structural modeling and molecular docking, it was found that three pivotal residues—Tyr156, Ser140, and His185—are critical for NADPH-mediated proton transfer, which facilitates the reduction of PAT (a toxic precursor) to the less toxic (E)-ascladiol (PMID:40984705 ). This reduction process highlights the importance of (E)-ascladiol in detoxification pathways, contributing to the metabolic processes that mitigate the effects of harmful substances in biological systems. The chemical structure of (E)-ascladiol features a double bond in the trans configuration, which is significant for its biological activity and interactions within metabolic pathways.
