Egg PG A84138 (Previously 841138) L-α-phosphatidylglycerol (Egg, Chicken) (sodium salt)

Egg PG, L-α-phosphatidylglycerol (Egg, Chicken) (sodium salt), is a naturally occurring anionic phospholipid found in plant, animal, and bacterial cell membranes. While less abundant than phosphatidylethanolamine in prokaryotes and eukaryotes and phosphatidylcholine in eukaryotes, Egg PG plays a key part in numerous biological processes.

Phosphatidylglycerol is synthesized through a reaction between CDP-diglyceride and L-α-glycerol 3-phosphate, followed by dephosphorylation, making it a key metabolic precursor of cardiolipin. Structurally, PG comprises two acyl chains esterified to a glycerol backbone linked to a phosphate-containing headgroup carrying a negative charge. This structure allows PG to form the second largest lipid component of mammalian lung surfactant, comprising 10 percent of its lipids. Notably, PG levels are reduced in the lung surfactant of infants with respiratory distress syndrome.

Avanti's Egg PG is noted for its exceptional purity (>99%) and consistent performance, making it a reliable choice for critical research and development projects.
