Description

1-Stearoyl-2-Palmitoyl-Sn-Glycerol is a structured triglyceride, a specific triacylglycerol molecule where the fatty acids stearic acid and palmitic acid are esterified at the sn-1 and sn-2 positions of the glycerol backbone, respectively. This precise molecular configuration is critical for research and development in lipid science, enabling the study of digestion, absorption, and metabolic pathways. It serves as a high-purity reference standard and a key synthetic intermediate for pharmaceutical, nutraceutical, and advanced food science applications where lipid structure dictates function.

Application

• Pharmaceutical Reference Standard: Used as a certified standard for analytical method development and validation in lipidomics and quality control laboratories.
• Biochemical Research: Essential for studying enzyme specificity (e.g., lipases), lipid metabolism, and membrane biophysics in academic and industrial R&D.
• Nutraceutical Formulation: Acts as a structured lipid precursor for designing specialized nutritional products, including infant formula and medical foods.
• Lipidomics & Metabolomics: Serves as a critical calibrant and internal standard in mass spectrometry-based profiling of complex biological samples.
• Cosmetic Science: Utilized in the development of high-end skincare formulations where specific lipid ratios are required for skin barrier repair and product stability.
• Food Science Research: Employed to model fat crystallization behavior, texture, and melting profiles in novel food product development.

Quality Control

Our 1-Stearoyl-2-Palmitoyl-Sn-Glycerol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) providing batch-specific data for identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. For daily use, allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation. Store in a cool, dry, and well-ventilated area away from incompatible materials.
