Abstract
Free-phospholipid fraction, extracted from Mytilus galloprovincialis 
and Mya arenaria was found to contein a higher ratio of metals (Na,K,
Ca and Mg) then the bind-phospholipid fraction (0,67 and 0,52 equiv.
metal/P - 0,25 and 0,16 equiv.metal/P. The metal ratio of the 
cephalines-rich fractions insoluble in ethyl alchol was found to be 
higher than that of the soluble ones; the values for free - lipids 
from Mytilus galloprovincialis were 0,18 and 0,93 equiv.metal/P.
Similar results were noted for vegetal phospholipids extracted from
sunflower and soybean 0,097 and 0,079 equiv.metal/P in lecithin
fractions: 0,97 and 0,695 in cephaline fractions.
