Incorporation of labeled choline into PC molecular species of the mouse lung (A, B, C, and F) and BALF (D, E, and G). Incorporation of [513C]choline derived from the hydrolysis of [U13C]DPPC is shown for the enrichments of total [513C]PC species in the lungs (A), individual [513C]PC species in the lungs from CHF5633- (B) and poractant alfa-treated mice (C), and individual [513C]PC species in BALF from CHD5633- (D) and poractant alfa-treated mice (E). Results were normalized for the enrichment of [U13C]DPPC in administered surfactant to enable a direct comparison between CHF5633- and poractant alfa-treated mice. The incorporation of methyl-D9-choline is shown in F and G for the lungs and BALF for CHF5633-treated mice. Results are presented as means ± SEMs.
