The two families of monosaccharides are aldose and ketoses

The two families of monosaccharides are aldose and ketoses. Monosaccharides are colorless, crystalline solids that are freely soluble in water but insoluble in nonpolar solvents. Most have a sweet taste. The backbone of common monosaccharide are unbranched carbon chain.
