In enzymology a phosphatidylcholine—sterol O-acyltransferase (EC 2.3.1.43) is an enzyme that catalyzes the chemical reactionphosphatidylcholine + a sterol 1-acylglycerophosphocholine + a sterol esterThus the two substrates of this enzyme are phosphatidylcholine and sterol whereas its two products are 1-acylglycerophosphocholine and sterol ester.This enzyme belongs to the family of transferases specifically those acyltransferases transferring groups other than aminoacyl groups.
