Microbial phospholipid membrane

The microbial phospholipid membrane is a lipid bilayer that constitutes the fundamental boundary of microbial cells, providing structural integrity, protection, and controlled exchange with the environment. Composed mainly of amphiphilic phospholipids (such as phosphatidylethanolamine, phosphatidylglycerol, cardiolipin), arranged in a bilayer with hydrophilic heads facing outward and hydrophobic tails inward, it is fundamental to maintaining cell viability. Embedded proteins permit transport, signal transduction, and energy conversion. In bacteria, the membrane's composition can be modulated in response to stress and thus represents a key vulnerability targeted by several classes of antibiotics and biocides. While not a receptor or enzyme, its functional role makes it a critical "therapeutic target" in infectious disease settings, though its name should be replaced with a more specific protein, enzyme, or molecular target for structured data use.
