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.

a main function of lipids is the formation of biological membranes cells are surrounded by a thin layer of lipids the layer is made up of a special type of lipid that has both hydrophobic and hydrophilic propertiesthe hydrophilic ends of these molecules face the water filled environment inside the cells and the watery environment outside the cellsa hydrophobic region exists inside the two layers the membrane that surrounds the cells is rich in proteins and other lipids such as cholesterolmost chemicals can not cross the lipid bilayer water and some other small molecules can freely pass through the membrane while other molecules must be actively transported via protein channels embedded in the membraneells are surrounded by a thin layer of lipids the layer is made up of a special type of lipid that has both hydrophobic and hydrophilic properties the hydrophilic ends of these molecules face the water filled environment inside the cells and the watery environment outside the cells
