Description

2-γ-Linolenoyl-1,3-Dilinoleoyl-Sn-Glycerol is a structured triglyceride (TAG) with a specific positional arrangement of γ-linolenic acid (GLA) and linoleic acid (LA) on the glycerol backbone. This precise molecular architecture is critical for advanced research in lipid metabolism, targeted drug delivery systems, and the development of specialized nutraceuticals. It serves as a high-value reference standard and a key intermediate for pharmaceutical, cosmetic, and nutritional supplement manufacturers seeking to innovate with structured lipids.

Application

• Pharmaceutical Research & Development: As a reference standard for analytical method development and validation in lipidomics studies.
• Nutraceutical Formulation: A key ingredient in the synthesis of specialized dietary supplements targeting specific metabolic pathways.
• Drug Delivery Systems: Utilized in the design and production of lipid-based nano-carriers (e.g., liposomes, solid lipid nanoparticles) for enhanced bioavailability.
• Biochemical Research: A substrate for studying enzyme specificity (e.g., lipases) and lipid metabolism in vitro.
• Cosmetic Science: Incorporated into high-end skincare formulations for its potential skin-barrier repair and anti-inflammatory properties.
• Food Science: Used in research for designing functional foods with tailored nutritional profiles.
