Description

1,2-Dioleoyl-3-Arachidonoyl-Rac-Glycerol is a structured triacylglycerol (TAG) featuring a specific fatty acid composition at each glycerol backbone position. This compound is of significant interest in biochemical and pharmaceutical research due to its role as a model substrate for studying lipid metabolism, lipase specificity, and the synthesis of complex lipid mediators. It is primarily utilized by research institutions, pharmaceutical development labs, and specialty chemical manufacturers focused on lipidomics, drug delivery systems, and the formulation of reference standards.

Application

• Biochemical Research: Used as a defined substrate for studying the activity and selectivity of lipases, phospholipases, and other lipid-metabolizing enzymes.
• Pharmaceutical Development: Serves as a key intermediate or model compound in the research of lipid-based drug delivery systems, including emulsions and nanoparticles.
• Lipidomics & Analytical Standards: Employed as a high-purity internal standard or calibration reference in mass spectrometry-based lipid analysis to quantify complex lipid species.
• Nutritional Science Research: Investigated for its metabolic fate and potential bioactive properties due to its specific combination of oleic and arachidonic acids.
• Specialty Chemical Synthesis: Acts as a building block for the synthetic preparation of more complex, structured lipids with tailored nutritional or functional properties.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and development. Each batch is characterized using advanced analytical techniques to confirm identity, purity, and lipid composition. Certificates of Analysis (COA) detailing purity, fatty acid profile, and critical impurities are available upon request. We adhere to a quality management system to ensure traceability and batch-to-batch consistency for our research-grade materials.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress. Keep away from strong oxidizers.
