Glycerol teichoic acid

WebLipoteichoic acid (LTA) is a linear polymer of phosphodiester-linked glycerol phosphate covalently bound to a lipid. The C2 position on the glycerol-phosphate is usually glycosylated or D-alanylated. LTA is amphipathic due to the presence of the negatively charged backbone of glycerol phosphate and the hydrophobic lipid.
