 note = {Phospholipase A activity was demonstrated in the homogenates of starfish visceral organs i.e. the pyloric caeca (L), the cardial stomach (C) and the gonads (E).  The highest activity was observed in (L) followed by (D) and the lowest activity was seen in (E). The main reaction products in the degradation of lecithin and phosphatidylethanolamine were monoacyl-derivatives and free fatty acids. The formation of glyceryl-phosphorylcholine and ethanolamine were not observed.      The experiments with α-(14C)-palmitoyl labelled substrate showed the presence of both Al and A2 types of phospholipase. A2 activity was predominant, and its optimum pH was around 7.4. Lecithin was hydrolyzed to a greater extent than phosphatidylethanolamine.},
