The recycling of phospholipids that are used as intermediates in the biosynthesis of other major membrane components is also crucial to bilayer stability in dividing cells. Here, the principal ...

A key experiment using the Langmuir trough provided the basis for accepting that the membrane is a bilayer and laid the groundwork for the current model of membrane structure. First, cells are ...

Lipid bilayer forms a water-impermeable barrier that defines the boundary of a cell and of specialized compartments within a cell. Membrane proteins are embedded in lipid bilayers and serve a wide ...
