Chapter 12 Carbohydrates

Chapter 12 Carbohydrates. Reduction to Alditols. The carbonyl group of a monosaccharide can be reduced to an hydroxyl group by a variety of reducing agents, including NaBH 4 and H 2 in the presence of a transition metal catalyst. The reduction product is called an alditol.
