Chapter 2.11, Problem 2MQ
Summary Introduction
The presence of outer membrane in a gram-negative bacteria provides only a modest strength to the cell. However, it plays a potential role in protecting the cytoplasmic membrane from several agents like lipophilic antibiotics and various substances harmful to the membrane. In addition to protein and phospholipid, it also comprises of polysaccharide. The polysaccharide and lipid molecules connect with each other to form a complex. Thus, the outer membrane is also referred to as the lipopolysaccharide layer (LPS).
