Taking in mind that composition and function of the natural lung surfactant differ among vertebrates depending on the pulmonary anatomy and respiratory surfacatnte and that its quality varies with the age of the animals, in the present work a biochemical and biophysical characterization of a pig lung surfactant from young and adult animals was studied in order to evaluate the quality of these surfactants.
