Description

L-A-Phosphatidylcholine, B-*Docosahexaenoyl-γ-St is a highly specialized, structured phospholipid where a docosahexaenoic acid (DHA) molecule is esterified at the sn-2 position of the glycerol backbone. This molecular configuration matters because it provides a superior, bioavailable source of DHA integrated into a critical membrane component, enhancing its functional efficacy in biological systems. It is primarily needed by manufacturers in the nutraceutical, pharmaceutical, and advanced lipid research sectors for developing high-end cognitive health supplements, infant formula, and drug delivery systems.

Application

• Pharmaceutical Excipient: As a key component in liposomal and nanoparticle formulations for targeted drug delivery.
• Nutraceutical Ingredient: In premium dietary supplements focused on brain health, cognitive function, and neuroprotection.
• Infant Formula Fortification: To provide a structured lipid source of DHA, mimicking human milk fat composition for optimal neonatal development.
• Biomedical Research: As a standard or reagent for studying membrane biophysics, lipid metabolism, and cell signaling pathways.
• Cosmeceuticals: Incorporated into advanced skincare products for its membrane-stabilizing and delivery-enhancing properties.
• Functional Food & Beverages: For the enrichment of foods with highly bioavailable ω-3 fatty acids.

Quality Control

Our L-A-Phosphatidylcholine, B-*Docosahexaenoyl-γ-St is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and assay, to ensure it meets stringent specifications for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and hydrolysis. The product is hygroscopic and should be handled in a dry environment. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
