Lesson 10 : Digestion and Absorption of Carbohydrates and Fats

Absorption of Monosaccharides

• Glucose and galactose are absorbed at a faster rate than fructose, and the pentoses are absorbed slowly, due to the fact that they are actively transported while fructose and pentoses are absorbed by diffusion.

• The absorption of monosaccharides depends on the presence of Na ions and also on the Na: K concentration ratio.
