The major subdivisions of monosaccharides are shown in Table 2.1.
Table 2.1 Subdivisions of Monosaccharides
| Class | Aldose | Ketose |
|---|---|---|
| Triose | Glyceraldehyde | Dihydroxyacetone |
| Tetrose | Erythrose | Erythrulose |
| Pentose | Ribose | Ribulose |
| Hexose | Glucose | Fructose |
| Heptose | Sedoheptose | Sedoheptulose |
Monosaccharides are soluble in water and insoluble in organic solvents. They are odourless crystals with a sweet taste. The chemical properties of these sugars are due to the presence of hydroxyl and carbonyl groups. Their sources, biochemical importance, and clinical significance are provided in Table 2.2.
