Which of the following lipids is associated with respiratory distress syndrome?
Phosphatidylethanolamine (cephalin)
Phosphatidylserine
Dipalmitoyl lecithin
Phosphatidylinositol
Dipalmitoyl lecithin is a very effective surface-active agent and a major constituent of the surfactant preventing adherence, due to surface tension, of the inner surfaces of the lungs. Its absence from the lungs of premature infants causes respiratory distress syndrome.
