Question

Use the picture of sucrose to answer the question about linkage. Thank you

**Question:**

How would you classify the linkage (α or β and carbon numbers) between the two monosaccharides?

**Options:**

- ○ 1,2 anomeric linkage
- ○ α-1,3 linkage
- ○ β-6,1 linkage
- ○ α-1,6 linkage
- ○ β-1,6 linkage
- ○ β-1,4 linkage

The question is presented in a multiple-choice format, asking about the type of glycosidic linkage between two monosaccharides. The options include various linkages, indicating whether the linkage is alpha or beta (α or β) and specifying the carbon numbers involved in the linkage.

**Does sucrose have an acetal grouping?**

The image shows the molecular structure of sucrose, which is a disaccharide composed of glucose and fructose units. The structure illustrates how these two monosaccharides are linked through an acetal linkage:

- **Glucose Unit:** On the left side, the glucose ring is depicted with its hydroxyl (-OH) groups and the CH₂OH group extending from the ring.

- **Fructose Unit:** On the right side, the fructose ring is shown, also with its OH groups and the CH₂OH group.

- **Acetal Linkage:** The central oxygen atom (O) is bridging the carbon atoms from each sugar unit, representing the glycosidic bond forming an acetal linkage.

In sucrose, this glycosidic bond is specifically an acetal linkage, which involves the linkage of a sugar molecule with one of its carbon atoms bonded to two oxygen atoms connected to different groups. Thus, sucrose does contain an acetal grouping.
