Biophysikalische Studien mit synthetischem Lezithin

Summary Synthetic lecithin, dissolved in chloroform, is able to add salts which are non-soluble in chloroform and to transfer these at neutral pH from the aqueous into the lipoid phase. The effect is dependent on the cation concentrations and particularly on their valency. Calcium, barium, copper ions, etc., are about one hundred times more effective than sodium and potassium. Two-basic amines are also very effective. For experimental reasons, anion was, up to now, not varied and in all tests tropeoline was used.
