Swelling of Phaseolus mitochondria induced by the action of phospholipase A
Phaseolus vulgaris mitochondria incubated in sucrose swell rapidly upon the addition of phospholipase A. Bovine serum albumin inhibits the swelling. The release of free fatty acids as a result of phospholipase A action on the mitochondria is detected only in the presence of bovine serum albumin, whi...

| description | Phaseolus vulgaris mitochondria incubated in sucrose swell rapidly upon the addition of phospholipase A. Bovine serum albumin inhibits the swelling. The release of free fatty acids as a result of phospholipase A action on the mitochondria is detected only in the presence of bovine serum albumin, which promotes the hydrolysis of both mitochondrial phospholipids and purified lecithin. Either free fatty acid or lysolecithin is able to initiate an extensive mitochondrial swelling in sucrose. It is suggested that phospholipase A-induced swelling results from the release of lysophosphatides plus free fatty acids and their subsequent detergent action on the membranes rather than phospholipid loss per se. |
