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.

Water and lipids are the two major types of solvent in the body. The lipid cell membrane separates the intracellular fluid from the extracellular fluid (as discussed in Section 2.1). Substances which are water soluble typically do not cross lipid membranes easily unless specific transport mechanisms are present.It might be expected that water would likewise not cross cell membranes easily. Indeed, in artificial lipid bilayers, water does not cross easily and this is consistent with our expectation.ubstances which are water soluble typically do not cross lipid membranes easily unless specific transport mechanisms are present.
