Description

1-Stearoyl-2-Lauroyl-Rac-Glycerol is a structured triglyceride, a specific triacylglycerol molecule where stearic acid and lauric acid are esterified at the sn-1 and sn-2 positions, respectively, on a glycerol backbone. This precise molecular architecture is critical for applications requiring controlled lipid digestion, absorption, and crystallization behavior. It serves as a key intermediate and functional ingredient for advanced research and product development in the pharmaceutical and specialty nutrition sectors, where lipid composition directly impacts performance.

Application

• Pharmaceutical Excipient: Used as a lipid matrix in the formulation of lipid-based drug delivery systems (LBDDS) to enhance the bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Nutraceutical & Medical Nutrition: A vital component in structured lipid formulations for specialized medical foods and parenteral nutrition emulsions, designed to provide specific metabolic pathways.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies (e.g., lipase activity assays) and metabolic research investigating lipid digestion and absorption.
• Cosmetic & Personal Care: Functions as an emollient and texture enhancer in high-end skincare products, contributing to skin barrier function and product stability.
• Food Science Research: Employed in studies on fat crystallization, confectionery fats, and the development of functional foods with tailored melting profiles and nutritional benefits.
• Lipid Chemistry Intermediate: Acts as a purified starting material or intermediate for the synthesis of more complex lipids, phospholipids, or other derivatives.
