Description

1,3-Dioleoyl-2-Palmitoyl-Glycerol is a structured triglyceride (TAG) with a specific fatty acid arrangement, where palmitic acid is esterified at the sn-2 position and oleic acid at the sn-1 and sn-3 positions. This precise molecular configuration is critical for its functionality as a high-value lipid ingredient in advanced nutritional and pharmaceutical formulations. It is primarily sought after by manufacturers in the nutraceutical, infant formula, and specialty chemical sectors for its tailored metabolic properties and role as a synthetic analog of human milk fat.

Application

• Infant Formula & Human Milk Fat Substitutes (HMFS): A key structured lipid designed to mimic the fatty acid profile and absorption characteristics of human breast milk.
• Clinical & Medical Nutrition: Used in enteral and parenteral nutrition products for patients with malabsorption disorders, providing easily metabolized energy.
• Pharmaceutical Excipient: Serves as a lipid-based carrier or solvent in drug delivery systems, including soft gelatin capsules and lipid nanoparticles.
• Nutraceutical Supplements: Incorporated into specialized dietary supplements targeting enhanced energy delivery and specific metabolic benefits.
• Biochemical Research: Used as a standard or substrate in lipid metabolism studies, enzymatic assays, and analytical method development.
• Cosmetic Formulations: Employed as an emollient and conditioning agent in high-end skincare products for its skin-compatible lipid properties.

Quality Control

Our 1,3-Dioleoyl-2-Palmitoyl-Glycerol is produced under strict quality management systems. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and fatty acid composition. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing results from tests including assay, positional isomer distribution, and impurity profiles. We support compliance with relevant standards for food and pharmaceutical ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at 2-8°C to minimize oxidation. For long-term storage, keep containers sealed in a cool, dry place. Allow the product to reach room temperature before opening to prevent condensation.
