Micelle phospholipid

Webb11 juni 2024 · As a result of this, the phospholipid head and tail form a micellar structure (micelles are small droplet-like structures). Thus, phospholipid in water has the capability to form micelles. Further, depending on the condition, these micelles can be single-layer lipidic spheres or bilayer lipidic spheres (which are better known as liposomes). Webbversible bilayer-micelle transition upon decreasing the temperature below the main-phase transition temperature tm of the respective pure phospholipid (7, 8). The detergent-phospholipid mixed micelles obtained after a sudden tempera-ture change from above tm to ’10°C below tm have not been fully characterized so far.
