13(S)-acetoxy-HODE methyl ester

13(S)-acetoxy-HODE methyl ester is a chemically synthesized ester derivative of hydroxyoctadecadienoic acid (HODE), specifically featuring an acetoxy group attached to the 13th carbon in the S-configuration and a methyl ester group at the carboxyl end. HODEs are metabolites of linoleic acid, primarily known for their roles as intermediates in lipid signaling pathways. The specific structure of 13(S)-acetoxy-HODE methyl ester allows for targeted research into the behavior and function of oxidized linoleic acid derivatives. This compound is commonly used in research to dissect the mechanisms of lipid peroxidation, a crucial biochemical process involving the degradation of lipids in the presence of oxygen, leading to the formation of complex signaling molecules that participate in various cellular responses. The acetoxy modification on the hydroxyl group and the methyl esterification of the carboxylic acid enhance the compound′s volatility and stability, facilitating its analysis using chromatographic techniques such as gas chromatography-mass spectrometry (GC-MS). This makes it particularly useful for studying the oxidative stability of lipids and their transformation products under various conditions. By applying 13(S)-acetoxy-HODE methyl ester in experimental settings, researchers can better understand the formation and action of lipid oxidation products in biological systems.
