Construct the most accurate summary of the final absorbable forms of the three macronutrients and their primary initial transport systems after intestinal absorption.

• A. All macronutrients are broken to single-carbon units and absorbed directly into portal blood where liver immediately packages them into HDL and LDL for distribution
• B. Carbohydrates become triglycerides and enter lymph, proteins become chylomicrons and enter lymph, lipids become sugars absorbed into portal blood
• C. Carbohydrates → simple sugars (e.g., glucose) → absorbed into blood (portal circulation); Proteins → amino acids → absorbed into blood; Lipids → fatty acids/monoglycerides reassembled into chylomicrons → absorbed into lymph
• D. Carbohydrates → fatty acids → absorbed into lymph; Proteins → glucose → absorbed into blood; Lipids → amino acids → absorbed into portal blood

Answer: (C)
