[The role of phospholipids and their fatty acids in the structural organization of membranes of plasmid-containing and plasmid-less Salmonella derby cells].
The effect of R-plasmid on the qualitative and quantitative compositions of phospholipids and their fatty acids in bacterial (S. derby) cells has been studied. It has been found that the lack of R-plasmid in bacterial cells leads to a sharp decrease in the phospholipid content, in the phosphatidylcholine content in particular, and causes an increase in the per cent content of lysophosphatidylcholines. The per cent content of saturated and nonsaturated fatty acids of phospholipids in plasmid-free cells does not change appreciably. In the plasmid-free strain of S. derby the intensity of lipid peroxidation is associated with a relatively high content of alpha-tocopherol.
