Chemical classification of carbohydrates entering the colon
The chemical classification of carbohydrates entering the colon is as follows:
●Monosaccharides: all except for glucose, fructose, and galactose are partly or completely unabsorbed. Fructose in the absence of a source of glucose (mono-, di-, or polysaccharide) is partly unabsorbed.
●Sugar alcohols: all are partly or completely unabsorbed.
●Disaccharides: all except for maltose, sucrose, and lactose are unabsorbed. Lactose is completely or partly unabsorbed in individuals with low intestinal lactase activity.
●Oligosaccharides: all are unabsorbed except for maltodextins.
●Polysaccharides: all nonstarch polysaccharides are unabsorbed.
