Small-chain fatty acids can enter the bloodstream directly, but large-chain fatty acids must be packaged first before entering the . can be carbohydrate-, protein-, or fat-based. remove cholesterol from tissues and deliver it to the liver for use in bile or excretion. Linoleic acid and alpha-linolenic acid are considered , and must be obtained from the diet. is needed to help mix fats with watery fluids. Carriers that transport monoglycerides and fatty acids to intestinal cells are called . contains 6 to 8 fatty acids connected to sucrose, and cannot be broken down by digestive enzymes.

Explanation:

Short-chain fatty acids can be absorbed directly into the bloodstream by the intestine capillaries, while long-chain fatty acids are released into the tiny intestine. Fat substitutes are chemical compounds that have similar properties of fats and oils, with fewer calories than fat. High-density lipoproteins (HDL) are referred as "good" cholesterol because they transport cholesterol from other body parts back to the liver. The alpha-linolenic acid and linoleic acid correspond to omega-3 and omega-6 fatty acids, respectively, and they are essential fatty acids that need to be consumed in the human diet. Emulsification is a chemical process consisting of mixing two immiscible liquids to form a semistable mixture. Micelles are chemical structures formed by the agglomeration of mixed lipids and bile acids, which support the action of lipases for digesting lipids. Olestra is a fat substitute that can be used in low-calorie diets for weight control. Finally, chylomicrons are ultra low-density lipoproteins (ULDLs) composed of triglycerides, phospholipids, cholesterol and proteins. The ULDLs are produced by intestinal cells.
