Analysis Note

Protein determined by biuret.

Application

Phospholipase A2 from bovine pancreas has been used to determine rat renal proximal tubular segments (PTS) viability during oxygenation and hypoxia-reoxygenation and to study the impact of phospholipase A2 on tubular cell triglyceride levels.

Biochem/physiol Actions

Hydrolyzes the β-ester bond of zwitterionic glycerophospholipids. Preferred substrates are phosphatidylcholine, phosphatidylethanolamine, and their plasmalogen analogues. Phosphatidylinositol and phosphatidylserine are also hydrolyzed. Aggressively attacks phospholipids in membranes of intact cells.

General description
