Description

1-Palmitoyl-3-Arachidoyl-Rac-Glycerol is a structured triacylglycerol (TAG) composed of palmitic and arachidic acids esterified to a glycerol backbone. This specific molecular configuration is significant for research and development in lipid science, offering a defined model compound for studying fat crystallization, digestion, and metabolic pathways. It is primarily needed by scientists and formulators in the pharmaceutical, nutraceutical, and specialty chemical industries for advanced lipid-based applications.

Application

• Biomedical Research: Used as a standard or substrate in studies of lipid metabolism, lipase enzyme activity, and membrane biophysics.
• Nutraceutical Development: Serves as a structured lipid ingredient in research for designing specialized nutritional oils with targeted release properties.
• Pharmaceutical Excipient: Investigated for use in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS) to enhance the solubility and bioavailability of poorly water-soluble APIs.
• Reference Standard: Acts as a high-purity analytical standard for chromatography (HPLC, GC) in quality control laboratories for lipid analysis.
• Cosmetic Science: Explored in the formulation of high-end skincare products for its emollient and structuring properties.
• Food Science Research: Utilized as a model fat to study crystallization behavior, texture, and melting profiles in food product development.

Quality Control

Our 1-Palmitoyl-3-Arachidoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. For long-term storage, keep the container sealed in a cool, dry, and well-ventilated area. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation.
