1. The phosphate esters of dimethylaminoethanol and monomethylaminoethanol can be incorporated from their cytidine diphosphate esters into the phospholipids of brain and liver dispersions; the deoxycytidine nucleotides of the same bases are less effective precursors. 2. The cytidylyltransferases of brain and liver are less effective in forming the cytidine diphosphate esters of monomethylaminoethanol and dimethylaminoethanol than those of ethanolamine and choline.

The ionic transport properties, capacitance and breakdown voltage of bilayer macrovesicles made from lecithin, dodecaprenol and their mixtures have been studied. The electrical measurements showed that polyprenol in lipid bilayers increases membrane permeability and elasticity, and decreases membrane thickness. Some physiological implications of these findings are indicated.
