What constitutes cell membranes?
That sounds interesting. Can you explain more about the different components of the lipid bilayer?
Yeah, the lipid bilayer is made up of phospholipids, which have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. Cholesterol is also present in cell membranes, which helps to maintain its structure and fluidity. Finally, proteins can be embedded within the lipid bilayer, acting as channels or pumps that allow for the selective transport of molecules in and out of the cell.
