WebDetergents are amphipathic molecules that contain polar or charged hydrophilic groups (heads) at the end of long lipophilic hydrocarbon groups (tails) ( Figure 1 ). They are also … WebDetergent or soap molecules have a very similar structure to the lipids in a lipid bilayer. They also have hydrophobic tail and a hydrophilic head but are usually assembled as a spherical structure (a micelle) in which the hydrophobic tails also point inward and the hydrophilic heads outward (Figure 4). Figure 4. Structure of a detergent micelle.

WebFeb 6, 2016 · The free detergent in solution is in equilibrium with the detergent in the micelle. The bag contains microscopic holes large enough for the monomeric detergent molecule to pass through, but small enough so that the large micelle can not. The lipid, during this process, is embedded in the micelle forming a detergent-lipid mixed micelle.
