Functions of Plasma Membrane Sphingolipids? The structure is similar to that of Glycero phospholipids except the presence of sphingosine backbone instead of glycerol. Location: abundant in the myelin sheath that surrounds nerve cells and the commonest sphingolipids is sphingomyelin. Glycosphingolipid...

Structure and Function of Fungal Plasma-Membrane ATPases The characteristic marker enzyme for the plasma membranes (PM) of almost all living cells is a cation-dependent ATPase of M r 100000 which has at least three crucial functions: maintaining ionic balance between the cell interior and the ....
The integral or intrinsic proteins account for 70% of the total membrane proteins and pass into the lipid bilayer to different depths. Some of them run throughout the lipid bilayer. They are called tunnel proteins which individually or in a group form channels for the passage of water ...

membrane, in biology, the thin layer that forms the outer boundary of a livingcellor of an internal cell compartment. The outer boundary is theplasma membrane, and the compartments enclosed by internal membranes are calledorganelles. Biological membranes have three primary functions: (1) they keep...
Although this membrane serves to protect the cell and its components, it's also surface through which substances are exchanged and information shared with other cells. Like the other cellular membranes, the plasma membrane is made up of lipids and proteins that contribute to the functions and char...

Portions of these transmembrane proteins are exposed on both sides of the membrane. Cell membrane proteins have a number of different functions...
