In fat malabsorption, which enteral component provides a concentrated source of energy?

• A. Free Amino Acids
• B. Fructooligosaccharides
• C. Medium Chain Triglycerides
• D. Long Chain Triglycerides

Answer: (C)

Medium chain triglycerides are favored in fat malabsorption because their shorter fatty acid chains (6–12 carbons) make them more water-soluble and they don’t require bile salts, micelle formation, or pancreatic lipase for digestion. They are absorbed directly into the portal venous system and transported to the liver, bypassing the lymphatic system and chylomicron assembly. This allows them to provide a concentrated, easily absorbed energy source even when fat digestion and absorption are impaired. In contrast, long-chain triglycerides rely on bile and pancreatic enzymes and are more dependent on the normal fat absorption pathways, making them less reliable in malabsorption. Free amino acids and fructooligosaccharides provide energy too, but they are not fats and are less energy-dense than fats.
