產(chǎn)品描述：Phospholipase A2 is a member of the class of heat-stable,calcium-dependent enzymes catalyzing the hydrolysis of the 2-acyl bond of3-n-phosphoglycerides. The enzyme has a molecular weight of 30,000 daltons.Phospholipase A2 is activated by Ca2+. It is inhibited by zinc, barium, andmanganese ions. Activity values for phospholipase A preparations which arederived from titrimetric assay procedures can be quite dependent on source andtype of lecithin, its preparation as a substrate emulsion, other components ofthe reaction mixture, and the method and instrumentation used
