| | 1.1 Membrane Structure and Composition |
| | Cholesterol is a necessary component of biological membranes. | | | Membrane proteins diffuse throughout the membrane in the same fashion, though at a slower pace because of their massive size (a phospholipid may be 650 d (daltons, or MW), and a medium sized protein can be 100,000 d). | | | This bilipid layer is semipermeable, meaning that some molecules are allowed to pass freely (diffuse) through the membrane. |

| | Electrohydrodynamic Interactions of an AFM Tip and a Biological Membrane |
| | In biological applications, AFM imaging needs to be performed in the natural (aqueous) living environment of the cell in order to observe molecular level interactions and biochemical processes in-situ in the electrolyte solution and to avoid the interference due to the capillary adhesion forces. | | | Despite significant advances made in experimental application of AFM in cell imaging, the data interpretation and associated theoretical models are still in its infancy. | | | The proposed theoretical methodology provides unique insight and quantitative information that cannot be directly measured during the AFM experiment, which are essential for interpretation of the imaging data. |

| | Definition of Peripheral membrane protein |
| | Therefore the so-called regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. | | | Peripheral membrane proteins are proteins that adhere only loosely to the biological membrane with which they are associated. | | | An exception to this rule is that cells may attach an "anchor" moiety, such as the fatty-acid anchor of lipid anchored proteins, which makes the purification properties of these proteins the same as integral membrane proteins, although researchers tend not to classify them as such. |
