Description

1-Palmitoyl-2-Linoleoylphosphatidylcholine is a specific, high-purity phosphatidylcholine (PC) species, a key structural and functional component of biological membranes. This compound is critical for research and development in advanced life sciences due to its defined fatty acid composition, which directly influences membrane fluidity, signaling, and stability. It is primarily needed by pharmaceutical, nutraceutical, and biotechnology companies for applications in liposome formulation, drug delivery systems, and as a reference standard in analytical studies.

Application

• Liposome & Nanoparticle Formulation: A primary phospholipid component for creating stable, uniform liposomes used in targeted drug delivery and vaccine adjuvants.
• Biomembrane Research: Used as a model membrane lipid in biophysical studies to investigate membrane permeability, protein-lipid interactions, and fusion processes.
• Pharmaceutical Excipient: Serves as an emulsifying agent and bioavailability enhancer in injectable and oral formulations.
• Nutraceutical Ingredient: A source of structured phospholipids in high-end dietary supplements targeting liver health and cognitive function.
• Cell Culture & Media Supplement: Used in specialized serum-free media to support the growth of sensitive cell lines.
• Analytical Reference Standard: Essential for the identification and quantification of phospholipids in complex biological samples using HPLC, LC-MS, or NMR.
• Cosmetic Actives Carrier: Employed in advanced cosmetic formulations for its skin-barrier repair and active ingredient encapsulation properties.
