It became the law of the land in 2010 and was named after Senator Christopher J. Dodd (D-CT) and U.S. Representative Barney Frank (D-MA), who were the sponsors of the legislation. But not all of the provisions are in place and some rules are subject to change, as we'll see.
Lipid bilayer is a universal component of all cell membranes. The structure is called a lipid bilayer because it composed of two layers of fatty acids organized in two sheets. The lipid bilayer is typically about five nanometers to ten nanometers thick and surrounds all cells providing the cell membrane structure.he structure is called a lipid bilayer because it composed of two layers of fatty acids organized in two sheets.

Another type of lipid in the cell membrane is CHOLESTEROL that makes the membrane more fluid. Embedded in the phospholipid bilayer are PROTEINS that also aid in diffusion and in cell recognition. Proteins called INTEGRAL proteins go all the way through the bilayer, while PERIPHERAL proteins are only on one side. Large molecules like PROTEINS or carbohydrates use proteins to help move across cell membranes.
