two particularly important observations were concerned with the complete stability of the three phospholipases on heating at 100 degrees c at ph 6.0 in the presence of 10 mm ca2+ , but variable stability in the absence of ca2+ , and the significant lack of hemolytic activity by the acidic ( pi 4.9 ) phospholipase a2 as compared to the neutral ( pi 6.9 ) and basic ( pi 8.7 ) enzyme which produced extensive hemolysis of human erythrocytes .
