Amino acids monosaccharides like glucose, electrolytes like Na+ are absorbed into the blood by active transport. Fructose and some amino acids are absorbed with the help of the carrier ions like Na+ by facilitated transport. Fatty acid and glycerol cannot be absorbed into the blood. They are first incorporated into small droplets called micelles, which move into the intestinal mucosa.
