Classification of Carbohydrates Monosaccharides or simple sugars >polyhydroxyaldehydes or aldoses >polyhydroxyketones or ketoses Disaccharides can be hydrolyzed to two monosaccharides. Polysaccharides hydrolyze to many monosaccharide units.E.g.,starch and cellulose have 1000 glucose units. => Chapter 23 3 Chapter 23 3 Classification of Carbohydrates • Monosaccharides or simple sugars ➢polyhydroxyaldehydes or aldoses ➢polyhydroxyketones or ketoses • Disaccharides can be hydrolyzed to two monosaccharides. • Polysaccharides hydrolyze to many monosaccharide units.
