Phospholipid hydrolysis
Did you know?
WebPhospholipase A (2) (PLA (2))-catalyzed hydrolysis of membrane phospholipids results in the stoichiometric production of a free fatty acid, most importantly arachidonic acid, and a lysophospholipid. Both of these phospholipid metabolites serve as precursors for inflammatory mediators such as eicosanoids or platelet-activating factor (PAF). WebActivation of this enzyme by one of the agents listed in the table causes the hydrolysis of a minor membrane phospholipid, phosphatidylinositol bisphosphate. Without leaving the membrane bilayer, the diacylglycerol next activates a membrane-bound enzyme, protein kinase C, that in turn catalyzes the addition of phosphate groups to a soluble protein.
WebAbstract. Upon storage of phospholipid liposome samples, lysolipids, fatty acids, and glycerol-3-phosphatidylcholine are generated as a result of acid- or base-catalyzed … WebJan 21, 2024 · By catalysing phospholipid using monomolecular film technique, sPLA2 released 1- lysophospholipid and a free fatty acid. These hydrolytic products were much more soluble than the phospholipid substrate, spread on monolayer film. Thus, they desorb on the aqueous phase, leading to a surface pressure decrease.
