Pulmonary surfactant reduces the surface tension of the alveolar air-liquid interface, thereby providing mechanical stability and preventing alveolar atelectasis. More than 50% of surfactant is dipalmitoyl phosphatidylcholine, a material that is capable of reducing the surface tension of the alveolar interface to uniquely low values.

Neonatal Surfactant Deficiency and Surfactant Replacement Therapy
International Journal of Technology Assessment in Health Care, 1991For the past 25 years, attempts have been made to treat respiratory distress syndrome (RDS) by administration of surfactant into the airways. This practice is not yet an accepted form of therapy. Lack of generally available surfactant during the present era of prospective studies will hopefully decrease the therapeutic misuse of this novel medicine.

Abstract: Alveolar pulmonary surfactant is a complex of macromolecular aggregates composed of phospholipids and surfactant proteins (SP) that is essential for maintenance of normal lung function. The importance of surfactant homeostasis is recognized in the patients and the animal models with pulmonary disease, although the mechanisms of surfactant ...

Journal of Colloid and Interface Science, 2009
Values of the area per surfactant molecule of various single chain and gemini quaternary ammonium surfactants containing biodegradable amide and ester groups are obtained from the surface tension measurements and they are mutually compared. It was found that surfactant molecules with the ester group in their structure occupy smaller area at the air ...

Microbial Surfactants: Alternative to Vegetable Oil Surfactants
2019Biosurfactants, surface active molecules synthesized by microorganisms, represent a promising alternative to the synthetic surfactants in many different applications. Among them, rhamnolipids have attracted considerable attention in the last years due to their extraordinary surface-active properties and biological activities.
