The Structure and Function of the Cell Membrane
The cell membrane is a fluid mosaic of lipids, proteins, and carbohydrates. In this tutorial we will describe these three structures and how they function in the cell membrane. This topic provides another example of the relationship between structure and function.
The Structure of Lipids Lipids are the one class of large biological molecules that does not include polymers. They are grouped together because they share one important chemical property: they have little or no affinity for water. The hydrophobic behavior of lipids is based on their molecular structure. Although they may have some polar bonds associated with oxygen, lipids consist mostly of hydrocarbons. Smaller than true (polymeric) macromolecules, lipids are a highly varied group in both form and function, and include such things as waxes and certain pigments. In this tutorial we will focus on three classes of lipids: the fats, steroids, and phospholipids.
