Description

[(3S,10R,13R,17R)-10,13-dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl] (9Z,12Z,15Z)-octadeca-9,12,15-trienoate is a high-purity, structurally defined sterol ester of α-linolenic acid (ALA). This compound is of significant interest for advanced research and development in the life sciences, particularly in the study of lipid metabolism, membrane biophysics, and as a potential precursor for specialized pro-resolving mediators. It serves as a critical reference standard and building block for pharmaceutical, nutraceutical, and biochemical applications where precise molecular structure is paramount.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and purity testing of sterol-ALA conjugates in drug development and quality control laboratories.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies related to sterol ester metabolism, lipase activity, and lipid signaling pathways.
• Nutraceutical R&D: Investigated as a potential bioactive ingredient or a metabolic precursor in advanced dietary supplement formulations targeting inflammation and metabolic health.
• Lipidomics & Analytical Chemistry: Employed as a high-purity calibrant and internal standard in mass spectrometry (LC-MS/GC-MS) for the accurate quantification of complex lipid species in biological samples.
• Membrane Studies: Utilized in model membrane systems (e.g., liposomes) to study the effects of specific sterol esters on membrane fluidity, permeability, and protein interactions.
• Chemical Synthesis: Acts as a key chiral intermediate or protected form for the synthetic preparation of more complex steroid-derived molecules and labeled analogs.
