Disaccharides, $\text{C}_{12}\text{H}_{22}\text{O}_{11}$, play an important role in the human diet. For instance, sucrose is present in pastries, while lactose is found in milk products. Each of these compounds may be hydrolysed. For sucrose: $\text{sucrose} + \text{H}_2\text{O} \rightarrow \text{CH}_2\text{OH(CHOH)}_4\text{CHO} + \text{CH}_2\text{OH(CHOH)}_3\text{COCH}_2\text{OH}$ (glucose) \hspace{1em} (fructose) For lactose: $\text{lactose} + \text{H}_2\text{O} \rightarrow \text{CH}_2\text{OH(CHOH)}_4\text{CHO} + \text{CH}_2\text{OH(CHOH)}_4\text{CHO}$ (glucose) \hspace{1em} (galactose) Which of the statements below about these hydrolysis products are correct?
- A1, 2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
