the currently available evidence suggests that dipalmitoylphosphatidylcholine , the major surface-active component of surfactant , can be synthesized in the alveolar type ii pneumocyte via two pathways : ( 1 ) by direct synthesis de novo via the cpdcholine route , and ( 2 ) by remodelling of unsaturated phosphatidylcholines , most likely via a deacylation-reacylation mechanism .
