Surface tension studies of phosphatidyl glycerol isolated from the lungs of Beagle dogs

Abstract

Abstract Phosphatidyl glycerol, isolated from Beagle dog pulmonary surfactant, was found to have surface tension properties similar to phosphatidyl choline (isolated from the same source and chemically synthesized). The results show that another phospholipid in addition to dipalmitoyl‐glyceryl‐phosphoryl‐choline contributes to the characteristic surface tension behavior of pulmonary surfactant.
