Hydrolysis of mixed monomolecular films of triglyceride/lecithin by pancreatic lipase.
The main purpose of this study was to describe the influence of lecithin upon lipolysis of mixed monomolecular films of trioctanoylglycerol/didodecanoylphosphatidycholine by pancreatic lipase in order to mimic some physiological situations. The quantity of enzyme adsorbed to the interface was simultaneously determined using 5-thio-2-nitro[14C]benzoyl lipase. Lipolytic activity was enhanced 3- t...
متن کاملSecreted phospholipase A2, lipoprotein hydrolysis, and atherosclerosis: integration with lipidomics
Phospholipase A(2) (PLA(2)) is a group of enzymes that hydrolyze the sn-2 position of glycerophospholipids to yield fatty acids and lysophospholipids. Of many PLA(2)s or related enzymes identified to date, secreted PLA(2)s (sPLA(2)s) comprise the largest family that contains 10 catalytically active isozymes. Besides arachidonic acid released from cellular membranes for eicosanoid synthesis, sev...
متن کاملEffects of colipase on hydrolysis of monomolecular films by lipase.
In a system free of bile salts we measured lipase hydrolysis of 1,3-didecanoylglycerol films in the presence or absence of colipase at different surface pressures. The strong, but not absolutely specific protective effect of colipase, most visible at low surface pressure, can account for the higher enzyme activity in the presence of colipase. This can be understood by taking into account simult...
متن کاملKinetic evaluation of cell membrane hydrolysis during apoptosis by human isoforms of secretory phospholipase A2.
Some isoforms of secretory phospholipase A(2) (sPLA(2)) distinguish between healthy and damaged or apoptotic cells. This distinction reflects differences in membrane physical properties. Because various sPLA(2) isoforms respond differently to properties of artificial membranes such as surface charge, they should also behave differently as these properties evolve during a dynamic physiological p...
متن کاملHydrolysis of milk fat globules by pancreatic lipase. Role of colipase, phospholipase A2, and bile salts.
Human milk fat globules require colipase to be hydrolyzed by pancreatic lipase in the presence of bile salts. This is contrary to a recent report in this Journal (J. Clin. Invest. 67: 1748-1752.) according to which inhibition of lipase by bile salt could be overcome by the addition of colipase or phospholipase A2. This latter finding is shown to be due to contamination of commercially available...
