13(S)-HODE cholesteryl ester

13(S)-HODE cholesteryl ester is a biochemically significant compound formed from the esterification of 13(S)-hydroxyoctadecadienoic acid (13(S)-HODE) with cholesterol. 13(S)-HODE is an oxidized metabolite of linoleic acid, produced enzymatically via the action of lipoxygenases that specifically generate the S-stereoisomer. This metabolite is crucial for studying lipid peroxidation and its influences on biological processes. The cholesteryl ester of 13(S)-HODE combines the hydroxy fatty acid with cholesterol, thereby enhancing its lipophilic properties and its integration into lipid membranes. This modification is particularly useful in research focused on the interaction of oxidized lipids with cell membranes, potentially affecting membrane fluidity, receptor function, and signal transduction pathways. By incorporating into cellular membranes, 13(S)-HODE cholesteryl ester can influence membrane dynamics and the behavior of membrane-associated proteins and signaling molecules. Researchers utilize this compound to explore how such oxidized lipids influence cellular responses under conditions of oxidative stress and to understand the role of lipid oxidation products in modulating cellular signaling. This exploration is pivotal in elucidating the complex interactions within cell membranes and contributing to the broader understanding of cellular adaptation to oxidative environments.
