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.

Movement of substances across the plasma membrane by protein carrier molecules (integral membrane protein) --used when molecule cannot cross membrane or crosses very slowly. --protein carrier molecules are embedded in lipid, and have site which specifically binds the molecules. --binding of the molecule to the site promotes a conformational change in protein carrier, resulting in transport of molecule across membrane.
