Formation of micelle Types of micelle 1. Spherical micelles qThese are micelles arranged in spherical form. qAmphipatic can form bilayers that sandwich the tails in the middle, or they can form spherical micelles q phospholipids are amphipathic molecules that contain two water-fearing tails qPhospholipids prefer to form bilayers qFatty acids have only one water-fearing tail, so forming a micelle is easier and more stable for them  2. Rod shaped micelle Monomers are arranged in rod shape Rod formation is primarily governed by the characteristic Gibbs free energy of rod formation Geometrically, a rod-shaped micelle consists of a central cylindrical part of the hydrocarbon radius and of more or less hemispherical parts at the ends of the hydrocarbon radius The model includes hydrophobic, electrostatic, and steric interactions Laminar micelle They are interconvertible In this type of micelle, monomers are arranged in laminar manner They are formed at higher concentration Initially micelles are of spherical type but as the concentration increases, it leads to the formation of laminar micelle
