Abstract:	Interaction of CDP-diglyceride with $Escherichia coli$ B membrane was studied by ESR spectroscopy. The results showed that the micelles of CDP-diglyceride molecules associate with membrane surface in the presence of Mg²⁺, whereas, when Mg²⁺ was omitted from the system, CDP-diglyceride molecules diffuse rapidly into membrane bilayer. The latter condition was shown to be more preferable for phosphatidylglycerol biosynthesis.
