Diagram phospholipid bilayer
WebLipid bilayers occur when hydrophobic tails line up against one another, forming a membrane of hydrophilic heads on both sides facing the water. Dynamics [ edit ] These specific properties allow phospholipids to play … WebThe lipid bilayer is the structural basis of all cell membranes and is nearly impermeable to ions and most polar molecules. Proteins embedded in the phospholipid matrix transport many substances through the membrane.

WebRecall that the general structure of a cell membrane is a phospholipid bilayer composed of two layers of lipid molecules. In archaeal cell membranes, isoprene (phytanyl) chains linked to glycerol replace the fatty acids linked to glycerol in bacterial membranes. Some archaeal membranes are lipid monolayers instead of bilayers (Figure 7).
