Phosphatidylcholines 0-19 phospholipase A2 group IB Homo sapiens 84-100 9148961-8 1997 We demonstrate that both phospholipase A2 and cholesterol esterase increase cholesterol uptake by hydrolyzing the phosphatidylcholine that is used to prepare the cholesterol-containing micelles. Phosphatidylcholines 114-133 phospholipase A2 group IB Homo sapiens 25-41
