Phospholipid Molecule, Lipid Bilayer, Micelle (colors) Cartoon Vector

A phospholipid molecule is a type of lipid that is a crucial component of cell membranes. It consists of a hydrophilic head and hydrophobic tails, which allow it to form a lipid bilayer structure. The lipid bilayer arrangement forms the basis of cell membranes, providing a selectively permeable barrier for the cell. In contrast, a micelle is another lipid structure formed by the aggregation of lipids, where the hydrophobic tails face inward and the hydrophilic heads face outward, creating a spherical shape. Micelles are often formed in aqueous solutions when the concentration of lipids is high enough to allow the formation of these structures.
