title: The effect of dexamethasone on phosphatidylcholine species composition in fetal rat lungs.
abstract: After dexamethasone treatment, a significant decrease in the monoenoic phosphatidylcholine 32 carbon species (palmitoyl-palmitoleylphosphatidylcholine and palmitoleyl-palmitoylphosphatidylcholine) and the phosphatidylcholine 34 carbon species (primarily palmitoyl-oleoylphosphatidylcholine) could be demonstrated both in absolute and relative terms, while the palmitic acid portion in the phosphatidylcholine fatty acids was nearly unchanged. This is in agreement with a significant reduction of the quantity of palmitoleic and oleic acids in the total phosphatidylcholine fatty acids.
