Description

D-1-Palmitin-2-Olein is a structured diacylglycerol (DAG) molecule, specifically a 1,2-diacyl-sn-glycerol, composed of palmitic and oleic acids. This specific regioisomer is of significant interest in advanced lipid research and specialty chemical applications due to its defined molecular structure and physicochemical properties. It serves as a critical intermediate and reference standard for the food, pharmaceutical, and oleochemical industries, where precise lipid composition and functionality are paramount.

Application

• Biochemical Research & Reference Standard: Used as a high-purity analytical standard for chromatographic calibration and metabolic pathway studies.
• Pharmaceutical Excipient Development: Investigated as a component in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS) to enhance drug solubility and bioavailability.
• Specialty Food Ingredient: Serves as a structured lipid intermediate in the development of nutritional supplements and functional foods with targeted metabolic effects.
• Oleochemical Synthesis: Acts as a key building block for the synthesis of more complex lipids, phospholipids, and surfactants with tailored properties.
• Cosmetic Formulation: Utilized in high-end skincare products as an emollient and texture enhancer due to its skin-compatible lipid profile.
• Enzymatic & Catalytic Studies: Employed as a specific substrate for lipase enzyme activity assays and selectivity studies.
