Lipolysis is the regulated breakdown of triacylglycerols, which involves three major enzymes. Name the enzyme based on its function described below. a) This enzyme removes the first fatty acid from a triacylglycerol molecule, which produces diacylglycerol (DAG) and a free fatty acid. It is stimulated through binding to its cofactor, CGI- 58. b) The removal of the second fatty acid during triacylglycerol breakdown is catalyzed by this enzyme, resulting in monoacylglycerol (MAG) and a second free fatty acid. It is activated through interactions with perilipin and must be phosphorylated by PKA for activity. c) This enzyme cleaves the remaining ester, resulting in free glycerol and a third fatty acid molecule. It is cytosolic and is not thought to be regulated by other proteins.
