Description

1-Palmitoyl-2-Arachidoyl-3-Oleoyl-Rac-Glycerol is a chemically defined, high-purity triacylglycerol (TAG) with a specific fatty acid composition at each glycerol backbone position. This structured lipid is critical for research and development in advanced lipid science, offering a precise molecular standard for analytical calibration and metabolic studies. It is primarily utilized by scientists and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries who require exact molecular entities for formulation development, biomarker research, and as a reference material.

Application

• Biomedical Research Standard: Serves as a critical reference standard in lipidomics for the identification and quantification of complex lipids in biological samples.
• Pharmaceutical Excipient Development: Used in the formulation of lipid-based drug delivery systems (LBDDS) to enhance the solubility and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Metabolic Pathway Studies: Acts as a substrate or tracer in research focused on lipid metabolism, digestion, and absorption mechanisms.
• Nutraceutical Formulation: Employed in the development of structured nutritional lipids and specialized dietary supplements with targeted nutritional profiles.
• Analytical Chemistry: Essential for calibrating instruments like HPLC and mass spectrometers in laboratories specializing in fat and oil analysis.
• Cosmetic Science: Used in high-end skincare formulations as an emollient and skin-identical lipid to support skin barrier function.
