<prompt> All of the following are phospholipids, EXCEPT?CardiolipinCerebrosideSphingomyelinSurfactant lipid  <response>: Phospholipids are those Lipids that contain phosphorus mainly as a phosphate group e.g. glycerophospholipids. Cerebrosides is group of glycosphingolipids called monoglycosylceramides. They Do not contain Phosphorus see fig below. Sphingomyelin is the only sphingolipid with a phosphate group. Surfactants are lipoproteinaceous substances synthesized in alveolar type II cells, which facilitate gas exchange by lowering alveolar surface tension. It contains significant amounts of phospholipid dipalmitoyl phosphatidylcholine.
