Description General description Phosphatidylcholine (PC) is the most abundant phospholipid in eukaryotes and a vital component of the mucosal layer of the colon. It is a strong bilayer-forming lipid. Application 17:0-20:4 PC has been used as an internal standard for the quantification of dipalmitoylphosphatidylcholine (DPPC) and palmitoyl-oleoyl-phosphatidylcholine (POPC), and as a quantitative lipid standard to monitor various lipid extracts concentration. Biochem/physiol Actions Phosphatidylcholine (PC) plays a vital role as a surfactant within the mucus to form a hydrophobic surface to prevents bacterial penetrance. It prevents the accumulation of triglycerides and the formation of lipolysis-resistant lipid droplets. Packaging 2 mL Amber Glass Sealed Ampule (LM1002-1EA)
