The hemolytic activity occurs only in presence of fatty acids (unsaturated fatty acids facilitate induce a strong hemolytic activity, whereas saturated fatty acids induce a slight activity). The inhibition of platelet aggregation is almost maximal when aggregation is induced by collagen, and arachidonic acid, whereas it is only of 30% when the aggregation is induced by ADP. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.<ref>PMID:23554559</ref> <ref>PMID:24678250</ref>
