Lipid Rafts—Composition, Characterization, and

Enrichment of phospholipids with saturated fatty acids allows for the close packing of lipids within rafts because 1) sphingolipids also contain saturated fatty acid side chains, and 2) cholesterol and saturated fatty acids are able to pack closely. As a result of the presence of cholesterol and saturated fatty acids, lipid rafts are more ordered and less fluid than the surrounding membrane.
