Description

1-O,3-o-Distearoyl-2-o-Palmitoyl-L-Glycerol is a structured triglyceride (TAG) with a specific fatty acid composition at the sn-1, sn-2, and sn-3 positions of the glycerol backbone. This precise molecular architecture is critical for applications requiring controlled lipid behavior, bioavailability, and physical properties. It is a key intermediate and functional ingredient for advanced research and product development in the pharmaceutical, nutraceutical, and specialty chemical industries.

Application

• Pharmaceutical Excipient: Used as a lipid matrix component in solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for drug delivery systems.
• Nutraceutical Formulations: Serves as a structured lipid in specialized medical nutrition and high-value dietary supplements to influence metabolic pathways.
• Biochemical Research: A vital standard and substrate in lipidomics research, enzymatic studies (e.g., lipase specificity), and metabolic pathway analysis.
• Cosmetic Ingredient: Employed in high-end skincare formulations for its emollient properties and ability to stabilize active ingredients.
• Reference Standard: Essential as a certified reference material (CRM) for the calibration of analytical instruments like HPLC and GC in quality control laboratories.
• Synthetic Intermediate: Used in the organic synthesis of more complex lipids, phospholipids, and other bioactive molecules.
