Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows.

Profilee Satyajit Mayor discusses his explorations of cell membranes, which are helping to update the classical fluid mosaic model of dynamic cellular boundaries. A series of rodent experiments showed ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Lipids are the most abundant organic compounds found in the brain and the main component of plasma membranes of nervous cells. In addition to their architectural functions for plasma membranes, lipids ...
