Lung phosphatidylcholine transfer in six vertebrate species. Correlations with surfactant parameters.
We have examined phosphatidylcholine transfer activity in lung-soluble fractions from six vertebrate species. There is a significant correlation between the amount of phosphatidylcholine transfer activity and both the alveolar surface area and surface active material. This suggested that phosphatidylcholine exchange proteins have a role in the lung surfactant system.
