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

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

Carbohydrates become triglycerides and enter lymph, proteins become chylomicrons and enter lymph, lipids become sugars absorbed into portal blood

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

Carbohydrates → fatty acids → absorbed into lymph; Proteins → glucose → absorbed into blood; Lipids → amino acids → absorbed into portal blood
