Description

1-Stearoyl-2-Palmitoyl-3-Oleoyl-Rac-Glycerol is a structured triglyceride (TAG) composed of specific fatty acids in defined positions on the glycerol backbone. This precise molecular architecture is critical for applications requiring controlled lipid behavior, such as in advanced nutritional formulations and pharmaceutical excipients. It is particularly valuable for researchers and manufacturers in the nutraceutical, specialty food, and cosmetic industries seeking tailored lipid matrices for product development.

Application

• Biomedical & Pharmaceutical Research: Used as a reference standard or model lipid for studying lipid metabolism, absorption, and the role of specific fatty acid positioning.
• Specialty Nutrition & Infant Formula: Serves as a key component in structured lipid formulations designed to mimic human milk fat or to deliver specific nutritional benefits.
• Excipient Development: Employed in the development of lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS) to enhance the solubility and bioavailability of poorly water-soluble APIs.
• Cosmetic & Personal Care: Acts as a high-performance emollient and texture enhancer in premium skin care products, providing unique sensory properties and stability.
• Food Science Research: Utilized as a substrate or model fat in studies investigating crystallization behavior, fat bloom in confectionery, and the physical properties of food lipids.
• Biochemical Reagent: Functions as a substrate for lipases and other lipid-metabolizing enzymes in enzymatic assays and industrial biocatalysis processes.

Quality Control

Our 1-Stearoyl-2-Palmitoyl-3-Oleoyl-Rac-Glycerol is produced under strict quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, GC, and NMR to confirm identity, purity, and fatty acid positional distribution. Certificates of Analysis (COA) detailing all relevant specifications are provided to ensure traceability and compliance with your research or manufacturing requirements.

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., nitrogen or argon) to prevent oxidation. Allow the product to reach room temperature in a desiccator before opening to minimize moisture uptake.
