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. The lipid bilayer is typically about five nanometers to ten nanometers thick and surrounds all cells providing the cell membrane structure.
The lipid bilayers that are found in cell membranes have two important characteristics. One of them is that most polar molecules cannot go across the membrane. Polar molecules are attracted to the water inside the cell or to the water outside the cell.However, they cannot interact with the nonpolar tails of the phospholipids within the lipid bilayer. The result is that the interior part of the cell membrane forms a non polar zone that acts as a barrier to polar molecules.hospholipids are molecules that make up the framework of the cell membrane..Phospholipids are lipids in which the long chains or tails are joined to a short polar head that contains phosphorus. The long tails are nonpolar, so water molecules will tend to push them away.
