  • Small fatty acids and glycerol cross into the bloodstream directlyLarger lipids are converted back to TG, are packaged with protein and called chylomicrons. These travel first to the lymph vessels.Some cholesterol (from food or bile) and some fat will become trapped in fiber, pass through unabsorbed.
