What are the macromolecules found in the cell membrane?

Plasma membrane is composed of lipids & proteins. A lipid bilayer obstructed by protein molecules at irregular intervals. It is known as fluid mosaic model. Lipid giving the fluid nature and the scattered proteins resembling a mosaic pattern. Or protein icebergs in a sea of lipid. read more

Cell membranes are primarily composed of a phospholipid bilayer. Amongst these layers there are proteins embedded both on the inner and outer surfaces and through the layer often acting as channels for other substances. The outer surface of the membrane contains carbohydrate chains attached to surface proteins. read more

The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and cholesterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant. In RBC studies, 30% of the plasma membrane is lipid. read more
