In molecular biology, substrate presentation is a biological process that activates a protein. The protein is sequestered away from its substrate and then activated by release and exposure to its substrate. [1] [2] A substrate is typically the substance on which an enzyme acts but can also be a protein surface to which a ligand binds. In the ...
Peripheral membrane proteins are temporarily attached either to the lipid bilayer or to integral proteins by a combination of hydrophobic, electrostatic, and other non-covalent interactions. Peripheral proteins dissociate following treatment with a polar reagent, such as a solution with an elevated pH or high salt concentrations. [citation needed]
The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure.
Cell adhesion molecules (CAMs) are a subset of cell surface proteins [1] that are involved in the binding of cells with other cells or with the extracellular matrix (ECM), in a process called cell adhesion. [2] In essence, CAMs help cells stick to each other and to their surroundings.
It contains a variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes.

Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.
