||"The OM [outer membrane] contains two types of lipids, lipopolysaccharide (LPS) and phospholipids, as well as a set of characteristic proteins (Table 1). In addition, the OM of Enterobacteriaceae contains a unique polysaccharide, enterobacterial common antigen (ECA)." "Furthermore, as the number of hydrocarbon chains in phospholipids is about equal to that in LPS in the OM (Table 1), most of the inner leaflet must be occupied by phospholipids and there should be few, if any, phospholipid molecules in the outer leaflet (primary source 176)."
