Long-chain triglycerides require bile salts for both digestion and micelle formation. Which category describes this requirement?

• A. Medium-chain fatty acids
• B. Short-chain fatty acids
• C. Long-chain triglycerides
• D. Medium-length glycerides

Answer: (C)

Long-chain triglycerides rely on bile salts for both digestion and micelle formation. Bile salts emulsify large fat droplets, increasing surface area so pancreatic lipase can act, and they help form mixed micelles that solubilize fatty acids and monoglycerides for transport to the enterocytes. Inside the enterocytes, these lipids are rebuilt into triglycerides and packaged into chylomicrons for lymphatic transport. Short- and medium-chain fatty acids are more water-soluble and can be absorbed directly into the portal blood without needing micelles or bile. So, this requirement characterizes long-chain triglycerides.
