Two common types of these compounds are SLS and DPPC, the latter of which is secreted by type II alveolar cells.
The HLB method gives values from zero to twenty for these substances that determines their properties. An extensively studied class of these substances from the bacteria Pseudomonas are rhamnolipids. These substances are modeled using the Gibbs adsorption isotherm, which has a knee and becomes constant at the CMC. Two common types of these compounds are SLS and DPPC, the latter of which is secreted by type II alveolar cells. When dispersed in a colloid, they aggregate to form micelles. These substances are classified as non-ionic, anionic, cationic, and amphoteric based on the polarity of their hydrophilic head group. For 10 points, identify these compounds that reduce the surface tension at an interface.
