The pancreas expresses and secretes various triglyceride lipases. (22) The predominant lipase is colipase-dependent pancreatic triglyceride lipase (PTL). PTL is the archetype of a lipase gene family that includes PTL homologues, pancreatic lipase-related proteins 1 and 2 (PLRP1 and PLRP2). (10) PLRP1 and PLRP2 are each present in pancreatic secretions. Also present is carboxyl ester lipase (CEL), alternatively known as bile-salt stimulated lipase (BSSL).
The lipases found in the gastrointestinal tract include lingual lipase (secreted by the serous glands of the tongue), gastric lipase (secreted by chief cells of the stomach), pancreatic lipase, and pancreatic lipase-related proteins 1 and 2. These enzymes generate free fatty acids and a mixture of mono- and diglycerides from dietary triglycerides. Lingual lipase and gastric lipase are the acid lipases and these function only in the acidic environment of the stomach.
In in vitro studies, the specific activity of lipases for glycerol phenylbutyrate was in the following decreasing order: pancreatic triglyceride lipase, carboxyl ester lipase, and pancreatic lipase–related protein 2. Further, glycerol phenylbutyrate was hydrolyzed in vitro by esterases in human plasma. In these in vitro studies, a complete disappearance of glycerol phenylbutyrate did not produce molar equivalent PBA, suggesting the formation of mono- or bis-ester metabolites.
