The outer membrane of Escherichia coli K-12 contained a smaller proportion of phospholipid molecular species with two unsaturated fatty acyl chains than did the cytoplasmic membrane. Proportions of phospholipid molecular species in the outer and cytoplasmic membranes changed in response to temperature changes. As the temperature increased, the content of 1-palmitoyl-2-cis-9,10-methylenehexadecanoyl species increased. Translocation of phospholipids from the cytoplasmic membrane to the outer membrane and synthesis of various molecular species were observed.
与细胞质膜相比，大肠杆菌K-12的外膜中含有两条不饱和脂肪酰链的磷脂分子种类比例较小。外膜和细胞质膜中磷脂分子种类的比例会随着温度变化而改变。随着温度升高，1-棕榈酰-2-顺式-9,10-亚甲基十六烷酰种类的含量增加。观察到磷脂从细胞质膜转运至外膜以及各种分子种类的合成。
