The lipid bilayer of a cell allows for selective permeability. This means that only the substances that are allowed to get in and out can pass through the lipid layer.
The plasma membranes of cells are largely composed of lipids, specifically phospholipids. These phospholipids form a bilayer structure that provides a barrier for the cell, regulating the passage of molecules in and out of the cell.
Membranes surround cells. There are no cells found in membranes. Membranes are composed mostly of lipids.
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Myelin is largely composed of lipids, particularly phospholipids and cholesterol. These lipids form a sheath around the axons of neurons, providing insulation and enhancing the speed at which electrical signals can travel along the neurons.
Cell membranes are composed primarily of phospholipids. These phospholipids form a lipid bilayer that acts as a barrier to the passage of most molecules. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.

lipids?
Lipids. Naturally there are many different types.
Lipids are generally not soluble in water and are an important component of biological membranes. They are composed of long hydrocarbon chains that make them insoluble in water but highly important for maintaining the structure and function of cell membranes.

Lipids are insoluble in water and found in biological membranes.
Lipids can be used to store energy. Some lipids are important parts of biological membranes and water proof coverings.
Phospholipids
Both lipids and sugars are impotent to membranes. Membranes are composed of phospholipids. They also contain glycoproteins, proteins that use sugars to help in communication between cells and identification.
