Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.
Pulmonary Surfactant. Surfactant is a complex substance containing phospholipids and a number of apoproteins. Surfactant reduces surface tension throughout the lung, thereby contributing to its general compliance. Pulmonary surfactant is a surface-active lipoprotein complex formed by type II alveolar cells.ottom left: the phospholipid 1-palmitoyl-2-oleoylphosphatidylcholine (POPC). Center right: sodium bis(2-ethylhexyl)sulfosuccinate (AOT) AOT is a rare surfactant-it is soluble and active in both oil and water.
