apparent values of km and vmax have been measured for catalysis of hydrolysis of unsonicated egg lecithin liposomes , activated through addition of 0.4 m n-hexanol , by phospholipases a2 from bee and snake venoms and by phospholipase c from clostridium welchii as a function of the concentration of three surfactants : hexadecylamine , hexadecyltrimethylammonium bromide , and dihexadecyl phosphate .
