Bacterial cell membrane phospholipid complex

The **bacterial cell membrane phospholipid complex** refers collectively to the diverse array of amphiphilic lipids—primarily glycerophospholipids—that form the structural basis of all bacterial cytoplasmic membranes. These complexes are not single molecular targets but rather essential components that create a semi-permeable barrier, regulate transport, maintain cellular integrity, and modulate interactions with proteins. The main classes include phosphatidylethanolamine, phosphatidylglycerol, cardiolipin, among others; their composition varies widely across species[5][6]. In Gram-negative bacteria, these complexes are critical for maintaining outer membrane asymmetry and function as a defense against antibiotics by preserving envelope integrity[1]. While not considered classical drug targets like receptors or enzymes, they are exploited by certain antibiotics such as polymyxins that disrupt their structure. However, "bacterial cell membrane phospholipid complex" is not a precise molecular target but rather describes an essential structural feature shared by all bacteria; thus it is too broad for use as a canonical therapeutic target name[1][2][5].
