Viral lipid membrane

The **viral lipid membrane** (or viral envelope) is a lipid bilayer derived from the plasma membrane or organelle membranes of the host cell during viral replication and budding[1][4]. It is a structural component of enveloped viruses, surrounding the viral capsid and genome, and embedded with viral glycoproteins necessary for host cell entry[1][4]. The lipid composition is typically enriched for certain lipids (such as sphingolipids and cholesterol) and exhibits domains that influence the mechanical properties, flexibility, curvature, and infectivity of the virus[1][4][7]. Alterations in this membrane can disrupt viral entry or egress, making it a conceptual but unconventional therapeutic target[7]. Lipid-targeting antiviral strategies remain largely experimental, with most approved antivirals focusing instead on viral proteins. **Note:** The viral lipid membrane is a structural feature—not a receptor, enzyme, or canonical macromolecular drug target. While it is targeted by some experimental therapies and physical interventions (e.g., lipidomimetics and detergents), it does not fit the standard definitions for drug targets such as "receptor," "enzyme," or "transporter." Therefore, **is_incorrect=true** for queries expecting a conventional molecular target.
