All long chain fatty acids require bile salts from the liver for lypolysis, which is the first step of their digestion. Once freed from the glycerol backbone, they are too large to move through the intestinal wall of their own. Instead, they must first be coupled with special proteins and cholesterol and chylomicrons (a type of cholesterol particle) for active transport through the instestinal wall, then carried to all cells of the body for metabolic use.
