Description

1,3-Palmitin-2-Linolein is a structured triglyceride, specifically a triacylglycerol where palmitic acid occupies the sn-1 and sn-3 positions and linoleic acid occupies the sn-2 position. This specific molecular configuration is of significant interest for its unique physicochemical and metabolic properties compared to randomized fat blends. It is primarily utilized in advanced research and development within the nutraceutical, pharmaceutical, and specialty food industries for applications requiring tailored lipid delivery systems and structured fats.

Application

• Nutraceutical Research: As a key ingredient in studies on structured lipids for targeted nutrition, infant formula, and medical foods.
• Pharmaceutical Excipient: Potential use in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS) to enhance the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Biochemical Standard: Serves as a high-purity reference standard for analytical chromatography (HPLC, GC) and metabolic research.
• Specialty Food Science: Investigated for modifying the physical properties (melting point, crystallization behavior) and nutritional profile of functional food products.
• Cosmetic Formulation: Used in high-end skincare products as an emollient and skin-conditioning agent with specific lipid properties.
• Metabolic Studies: Essential for in-vitro and in-vivo research on lipid metabolism, absorption, and the impact of fatty acid positioning.
