Lipid II is a crucial molecule in the synthesis of bacterial cell walls. It serves as a building block for the peptidoglycan layer, which provides structural integrity to bacterial cells. Lipid II is a membrane-anchored molecule consisting of a disaccharide linked to a pentapeptide, with a lipid tail that anchors it to the cell membrane. This unique structure makes it a key target for antibiotics aiming to disrupt cell wall synthesis.
