Why can molecules that are fat-soluble permeate across a cell membrane?

Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.


What is the basic macromolecule that all cell membranes are composed of?

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.The phospholipid bilayer also contains cholesterol.All cell membranes are composed of:PhospholipidsProteinsCarbohydratesCholesterol
