Description

1-Stearoyl-2-Oleoyl-Sn-Glycerol is a structured triacylglycerol (TAG) with a defined stereochemistry, where stearic acid is esterified at the sn-1 position and oleic acid at the sn-2 position. This specific molecular architecture is critical for research and development in lipid science, providing a pure and well-characterized standard for studying fat metabolism, crystallization behavior, and emulsification properties. It serves as an essential biochemical tool for pharmaceutical, nutraceutical, and advanced food science laboratories focused on lipid-based drug delivery systems, infant formula, and specialty nutritional products.

Application

• Biochemical Research Standard: Used as a high-purity reference compound for analytical method development, lipidomics, and metabolic studies.
• Pharmaceutical Excipient: Investigated as a component in lipid nanoparticles (LNPs) and self-emulsifying drug delivery systems (SEDDS) for enhancing drug solubility and bioavailability.
• Nutraceutical Formulation: Serves as a structured lipid model in the development of specialized nutritional products, including infant formula and medical foods.
• Food Science Research: Employed to study the physical properties of fats, such as melting profile, polymorphism, and stability in food matrices.
• Cosmetic Ingredient Intermediate: Acts as a precursor or model compound in the research of emollients and stabilizers for personal care formulations.
• Enzymology Studies: Used as a specific substrate for lipases and phospholipases to study enzyme specificity and kinetics.
